3000GT Stealth DIY: Coils, IAC, Spark plug, Wire, PTU replacement

[@grantcleveland1]

Great vid. Thanks for taking the time! Its nice to work on a crusty car (no offence). Most of the 3S vids are from new clean builds so this one is great for the real world

You have no idea how helpful this was for me. Trying to work on a 31 year old car in the winter is a pain but you made it manageable

[@felipefernandezlomas6770]

Kudos on getting the rear plenum bolt in so quick. I think my record is about 45 minutes 🤣

[@calid6960]

I know this is an old video, but he made that whole process more work that needed to be done. I do mechanic work and I've worked on dodge stealth aka Mitsubishi 3000gt and you don't have to go through all the difficulties he did.

[@bennplaisance]

I hear that phrase "I'm a mechanic" way too often. Everything in this step by step guide was necessary to have clear access to everything that was changed.

[@calid6960]

@@bennplaisance I work for a mechanic shop,so it's no phrase,it's fact.

[@calid6960]

@@bennplaisance I love when individuals make general assumptions and don't know the facts,kind of like you did when you said people use the 'phrase'". I don't phrase to be something that I already am. I'm an actual mechanic ,point blank. You should never generalize people, because it makes you look unwise when you don't know anything about them.

@calid6960 ok. I'm an ASE master technician, been in professional dealerships for over 11 years, master kia, master hyundai (when they were still using mitsubishi engines just about identical to these), silver chrysler, and now coming up on master nissan here shortly, trained numerous other techs to be able to start out on their own, been heavily working on twin turbo 3000gts and stealths since 2008, in fact rebuilding my white twin turbo was the first car I've ever worked on. This is exactly the amount of work that needed to be done for all the parts I changed. There are no unnecessary steps here. Sure I could of sneaked the ignition coil, ptu, and iac out of there without taking the intake or intercooler pipes off, but then it makes it harder to show what bolts I'm taking off and it also makes it harder on the people watching that don't do this for a living.

[@calid6960]

@@bennplaisance got cha. Don't get me wrong, I wasn't being critical in a mean way I was just saying it seemed more difficult than it had to be,especially for people who hasn't worked on stealth. I'm 54 and like you I've been working on cars for a very long time. But again wasn't being critical to be mean.

@18:49 ,what is the name of the control valve he is replacing? i cant understand what he says.... thanks

[@bennplaisance]

Idle air control valve

[@eddylebrun9717]

Can anyone send me a video on how to change the fuel line at the back of the brake cylinder

[@vr4rock]

thanks for info man I change mine thank u so much for guide

[@daninavarro204]

After I installed a new ptu, the tach rpms started fluctuating when I accelerate any idea what it could be? I was thinking a new IAC valve but I’m not sure

[@bennplaisance]

The tach only gets signal from the ptu, either loose/corroded connection, faulty tach, or faulty ptu. That's if the tach is doing funny things with no driveability issues

[@jvst20051]

Do they still sale the coil new or we just gatta get them used

[@bennplaisance]

There are new oem coils and ptus, and there are also aftermarket ones

[@jvst20051]

@@bennplaisance where u get the ptu I

[@bennplaisance]

3sx has the coils and ptu

[@jvst20051]

Whats that little capacitor you call condensor for?

[@bennplaisance]

Just to reduce noise interference and possibly help protect other electronics from voltage spikes

[@sfcmtz]

On my 1994 vr4 I had a hesitation between 2700 and 3100 rpm. Sometimes it was worse than other times. I replaced plugs and wires, air filter, and did the full 60k mile timing belt and water pump service. It didn’t help. I decided to fire up the parts cannon and I ended up buying a rebuilt ecu off eBay. Problem solved. The capacitors in many of our old electronics are failing. Replace them and your problems may be fixed. My car is 84k miles always garage kept btw. Not modified or abused at all

[@randomdiy3823]

Did you have your new ECU reprogrammed before you install in your car?

[@MasterjngReizowolf]

noted, thanks.

[@1magnit]

Coils don't get weak internally.

[@bennplaisance]

Failing Ignition Coils can have high internal resistance causing a weak or no spark. The windings begin to break down from age, heat, and moisture. A failing Ignition coil doesn't have to arc outside the casing to be faulty Our factory ignition coils are very good, and seem to last a long time but they can still start producing weaker or no spark over time.

[@eddylebrun9717]

That's in the engine bay against the firewall

Dammmmn nice TT. I got a 91 non turbo rt.. wish I had the TT;)... i wish I could figure out what the hells wrong with it even more lol
