Zafira A 1.8 16V (Z18XE) running poorly

[@davidberrey7900]

Hi bud my vectra c had the same fault after cleaning the throttle body and after a couple of hours I figured out that when I put the body back on the gasket had twisted slightly and was letting air in thus causing it to run rough on tick over I purchased a new gasket off eBay I assembled it very carefully making sure it sat correctly and wa la she ran sweet as a nut try that first check that gasket make sure its not sucking air by using easy start around throttle body base if it revvs up when you apply it then that's your problem

[@Swb2373]

Done a z16xe a few years ago same symptoms, was sticking valves. A good decoke and stem seals sorted it.

[@mumtaz1977]

Same problem here. Throttle body cleaned, but nothing. ECU changed, because other problems. So. Any suggestion? Vacuum pipes, inlet or perhaps PCV valve?

[@MrRohanThomas]

Check vacuums, maybe disconnect MAF sensor connector and see if it runs better

[@bassboosted3480]

What was wrong?

[@enzogatto8029]

sound as if the coil pack is missing the insulators crack and break thus shorting to ground or just coil pack pcb failing if the insulators are cracked they can be repaired using heat shrink tubing as they are not a spare part hope this helps Enzo

[@madyottoyotto3055]

Not enough vibration for missfire However it could be missing on two them it wouldn't vibrate

[@sschilthuizen]

I had four ripped fuel injectors , so i think it is a construction error or the manufacterer never pushed down hard enough on the injectors but used the bracket and bolts to push all of the injectors down.

[@DaMan1964]

1:51 stud with no nut means some one other than a mechanic has worked on it so It could be anything. You`d wanna do a thorough diagnosis including comp test and check EVERYTHING with the intention of restoring it to as per factory. If you look at the ends of the spark plugs it should indicate by color and deposits how the engine is burning fuel.

[@ReconcilineGamibeb-i4u]

Hi I have the same car it only goes up to 300mhp why!! Please help

[@davehitchman5171]

My 1.6 has a habit of breaking the spark plugs, when it breaks one it runs like its broken the crankshaft and everything. It did also once manage to end up with a half dead coil pack, lots of warning lights, zero power, running rough, not at all happy

[@madyottoyotto3055]

My guess would be the pcv (positive crank ventilation) valve is clogged and/or leaking air two take silver cover of and you should see black circle above oil filler I think from memory see of you can here a vacuum leak But also disassemble it to check the diaphragm hasn't split

[@jamesmiller113]

RIP that Zaf :(

[@DrewKrewTube]

lol yup, it got taken to the scrappy a few months ago. Never solved the problem.

[@jamesmiller113]

On mine it turned out to be a loose air-line on one of the cylinder inlets, same symptoms as that though

[@gregorteply9034]

Fuel mixture is all we've got a leak in your air system somewhere along your body work so I am yeah good luck on that one

[@alexandracercel4026]

My car is a Astra g bertone 1.8 16 v ... and i have this problem .. help me plz

[@jarleandrejohansen4739]

Had poorly runnig zafira. Error codes are often not very spesific, but only suggest a list of items to check: MAF, lambda/O2-sensors, EGR-valve, ignition module, etc. Nothing worked. On my engine it complained about cylinder 3 misfire. Could first not find any faults, but on closer inspection an almost invisible gray soot spot revealed a tiny sparc burn through on the ignition module spark plug connection insulating pipe. The hole was on top and partly behind the rubber seal between the pipe and the spark plug. I reparied the hole with glue and high temp, high voltage crimp insulation. Has been running smoothly after.

[@Actiune]

Cylinder 3 misfireing could be 90% ecu internal fault (it has very thin wires and in time and vibrations those wires break contact) you should check with a LED (not a light bulb) to see the command for injector 3. It has permanent + and grounded by ECU.

[@SoundSpence]

Sounds wierd, but I had this on my Zaffy, and it turned out that there was a vacuum pipe which was disconnected, make sure all inlet and vacuum pipes are all on and not split!

[@drewsuttle2398]

Very good point. On another 1.8 Zafira i had that same problem after it was pulled loose cleaning the air intake ducting. Unfortunately wasn't the problem with this silver one.

[@philipryan3195]

yer me too

[@MrRohanThomas]

same

[@freagle123]

My Zafira 1.8 has had the same problems as in the video since the day before yesterday. But only after I changed the spark plugs and air filter. At first I thought it was the ignition coil and installed a new one, to no avail. After reading this I hope I just accidentally loosened a hose when changing the air filter. Update: I found the error on mine. When I was changing the air filter, I unnoticed loosened a hose that goes into the intake manifold. Today I put the hose back on and it's running again, only the check engine light is still on, but that should be the minor problem. I only found the error thanks to your comments and even though you may not be reading this because your comments are a few years old, I thank you very much.

[@javiern3036]

you can heard the leaking ear noise, check the pipe going from the evap valve to the throttle. is the valve behind the air filter box. in my one was disconnected at the throttle body, and y was having the same problem tam you. I hope it helps

[@Actiune]

Right ! Could be also the rubber elbow fitting at the end of the plastic tube. Mihe was cracked severly and I did repair it with self sealing rubber band. Cheers

[@joeazigazi1802]

Did you find out what the error was?

[@strangeperson700]

Try reflashing or replacing the ecu, if all of your coil packs are being spoilt a month after replacing them then your ecu could be cooking them. The ecu units tend to fail on these engine designs because the designers put the ecu right next to the engine.

[@matthewking5612]

Was a stupid design, lovely engine though.

[@strangeperson700]

@@matthewking5612 There is a way to extend the wires and pass all of the wires through the firewall of the car, that way you can keep the ECU inside of the driver's compartment, underneath the glove box, or somewhere in the dashboard.

[@matthewking5612]

@@strangeperson700 Interesting, my car's not nice enough to justify such effort. If it goes I'll either have it refurbished, or just scrap the car.

[@mrdannymcgee5321]

My astra had misfire problem the cause was a fuel purge valve being broken stuck open bought another one that fix the problem

[@paulstyring1015]

That strange thing is the pcv or purge valve and its most likely the cause of the running issue.Its probably stuck open and pulling air in from the tank...the lean code is a clue.

what was the issue?!?!?! :( :( i live in australia where they are called holden astras, mines doing the same thing :(

[@adclawrence9697]

Hayden Hayes My Astra had the same thing, nearly stalling and revving itself, then stalling again. Ended up being dirty airflow sensor and throttle body.

[@haydenhayes4128]

adclawrence thats exactly what my issue ended up being too lol,

[@haydenhayes4128]

did you happen to get a code that read catalyst damage (but the cat wasn't damaged)

[@adclawrence9697]

I didn't get any warning lights or codes. At least the mechanic didn't check for codes, but there certainly was no light. It just stuttered and idled rough. After cleaning the sensor and throttle body it ran just fine.

[@haydenhayes4128]

yeah it runs like a dream after doing that, its been about 2 months and I'm thinking the throttle body might need another clean because its doing it again but only so slightly (the rev dropping when turning off the airconditioning )

[@olemller9725]

Hola buen día me pueden decir porque se baja y sube las revoluciones de mi Opel Zafira 1.8

[@lyriccall]

Hay varias cosas por hacer, yo tengo Meriva A 1.8 16v 2008. primero los capuchones de bujía fugan chispa, eso te causa misfire (p03xx), lo solucionas. Luego te sale en problema de las RPM, parte 1: desmontas todos los conductos de aire, revisas que no estén rotos, quebrados o gastados donde se unen a las otras piezas, en mi caso coloque cinta aislante (varias capas) en las uniones y las coloque a manera de empaque, asegurándote que queden las marcas alineadas. Parte dos: hacer el aprendizaje del cuerpo de aceleración, yo uso el op-com (clon chino de MercadoLibre.com.mx o de ebay.com *es el mismo) Después te sale el service engine alternado con check engine (El motor y el motor con la llave mecánica). Después de batallar algo te das cuenta que el sensor MAF tiene mucha vibración ya que cuelga de la carcasa del aire acondicionado y del motor (una parte que se mueve y la otra no) moviendole me di cuenta que el arnés está flojo y causa perdida de potencia, o sea aceleras y no responde el motor acelera lento. Ya de ahí solucionas muchas cosas. Mí Meriva es Easytronic, así que cada fallo en el motor se refleja en códigos de error en la transmisión, resuelve el problema del motor y se van la mayoría de los códigos de transmisión (te dice not present) Si aún tienes problemas puedes hacer varias cosas con la transmisión: Hacerle aprendizaje del clutch que lo haces al final de solucionar todo ya que depende de la potencia del motor y si tienes el problema en el motor te va a dar otro código de error.

have you figured out what the issue was?

[@DrewKrewTube]

Dave Davus no, i gave up on the vehicle after two months of trying many new parts. Have no idea why it went so bad.

[@jayh4822]

forgot I had commented on this, I did figure out the problem apparently its a common fault with the earthing inside the ECU to fix it I had to ground the throttle body to the ECU along with the accelerator pedal.

[@Nikolo8D]

Hello Jay, can you elaborate more on how to do this? Do you pull a separate wire from the throttle body ground pin to the negative pole on the battery? And then do the same on the accelerator pedal sensor? Cheers Nikolo My 2004 Opel Zafira 1.8 petrol will crank but not start. Before this happened I had same symptoms as the video. In the beginning the car had bad acceleration and bad fuel economy and I could not keep it at a steady speed on the highway. I have changed the MAF sensor (brand is Johns autoteile), fuel filter, cleaned throttle body (and the little hole), and also got a new second hand throttle body. I believe fuel pressure is ok because fuel comes out when I press the valve on the fuel line. It has a new battery and I do have spark. I once got it to idle, which was rough idle like the video. Will try to change the crankshaft position sensor. I believe the EGR valve has been blanked off, which is located above the gearbox. Maybe I need to keep looking after air leaks.

correct. but the exhaust dirts over time can block the very small exhaust recirculation channels inside the intake manifold. Needs to be cleaned (means removing/opening, since sprays poorly can do their job there...) Had this on my Z18XE Astra convertible.
