I'm glad you said which side was which. Cause the video is backwards

Hello! My car, 2007 GL450 and looks like yours in the video. The Engine Coolant Temperature Sensor needs to be replaced. I got the part from Lordco, but I could not find the location of the sensor. The task should be easy and straight forward, but each car and model year has a different location. Please help me find it. Thank you so much for your help.

I replaced all coils, spark plugs and injectors, still has misfire one cylinder 1 and 4 , what the next thing I can do ?

[@freddycamacho4334]

Hi Brother, great video. I have a similar problem. I replaced all my coils and spark plugs and then got code p0351, p0355, p0351 P and p0355 P. Which are position 1 and 5, coil and plugs. Swapped coils and replaced plugs and still got the codes on the same spots. Could it be the wire harness? Do you have any other suggestions for troubleshooting? Thanks

I have a misfire on my GL450 2007. Took it to the shop to have a Schedule B done. After the oil change and new plugs become needed them done. I had a misfire on cylinder 1 so I took it back and then he switched ignition coil 1 and 3. So now its reading cylinder 3. Bad coil correct? So I bought new coil and replaced number 3 still getting the hesitation sometimes. Should I replace cylinder 1 as well or not? Thanks

[@MunkysGarage]

I would check and see if you have a pending misfire fault for another cylinder. If not you are taking a shot in the dark on which cylinder would be causing the intermittent misfire. You may be at the point that you are going to start having ignition coils go bad due to mileage or age and this may be an ongoing thing until you replace all of them.

@@MunkysGarage Thanks for the information. The vehicle has 97,000 miles. The mechanic told me they should have been replaced at 91,000. I had no check engine light on until the new plugs. So does it matter if I buy the plugs from an auto store or should I go to the dealership?

[@rachelsstar9794]

Please can this cause me my engine. My mechanic checked everything and is still shaking. So he said may be something is broken there. And I need to buy new enging

Hello sir! can i know the standard value of the maf sensor (in the scantool data) on an gl x164 m273 accuratly?! is it to 6 g/s as maximum ? and thanks.

[@MunkysGarage]

Rule of thumb on maf g/s at idle should be at or slightly over engine displacement. So with thst being s 4.7 L engine, you should see somewhere between 5-6 g/s at idle.

@@MunkysGarage Thanks sir! 🎩

[@umaira.5662]

What mileage is on the gl450?

[@MunkysGarage]

It currently has around 218k miles on it.

[@Trashpanda_404]

What scan tool is that?

[@MunkysGarage]

Matco Maximus MaxLite. They no longer sell that version. They sell an updated version called the MaxLiteA. Here is a link to it. www.matcotools.com/catalog/product/MDMAXLITEA/MAXIMUS-LITEA-DIAGNOSTIC-SCAN-TOOL/
