It isn't the MAF the code reader says the system is running lean. I just want an idea of what sensors could affect this besides the MAF. Maybe a vacuum leak? Any ideas before I go back to my friends shop tomorrow to pull the code and start throwing parts at it again, haha. I would check the trouble codes but I don't remember what the reader said. Sorry.

Thanks in advance.

Possible PCV hose leak or intake gasket leak.

 

How is an effective way to check for either of those. I know how to check the PCV but what about the intake gasket? Any way to check for that? Could it possibly be an o2 sensor? The code reader throws two codes, one for the #1 cylinder bank and one for the #2 cylinder bank. Both running lean. I tried the injector cleaner. Any other ideas?

 

What is the intake gasket? The intake MANIFOLD gasket? If so, then damn. I'm pretty sure its a leak now, I can hear a constant hissing sound when the hood is up while its running but I can't seem to find it. Any ideas?

 

intake gasket goes between the intake and heads

 

DAMN that sounds like a pain in the ***.

 

A few days ago I had the trouble code "Bank 2 running too lean." I replaced the drivers side oxygen sensor, (real easy to get to if you take the tire off), then I erased the trouble code and the Check Engine light hasnt come back on yet. "Bank 2" means the side of the engine that does not have Cylinder #1 on it. In other words, driver side.

Autozone had O2 sensor with the longest wires for $50. Sensors with shorter wires were $30 and $40. I bought the longest one just in case and only needed the shortest one.

 

I'm doing all the gaskets, then the wires and plugs. That should take care of it, but if it doesnt then I'll go to the o2 sensors. I'm taking care of all the maintenance right now doing this, so its not too big of a deal I guess. Thanks for the input.

 

My check engine light just came back on yesterday.

 

O2 sensors don't cause lean codes.

Leaking lower intake gaskets and isolator bolts do.

 

What are isolator bolts? Is it possible my engine is getting too much air?

 

The isolator bolts secure the lower portion of the plastic intake to the lower aluminum intake. They have rubber gaskets on them that are black in color and are usually the cause of vacuum leaks. The service isolator bolts are green and seal up better. Usually what happens is the isolator bolts and/or intake gaskets leak on cold start up, and as the engine warms up the rubber seals swell and quit leaking.

 

I'll have to look into that. Than Quintin.

 

dont forget to reset your keep alive memory on the computer.basically remove
both battery cables and toch them together,Let vehicle set so the computer has time to discharge and reset.if you dont do this the computer will think it still has a problem.This is cheaper than going to dealer to get pcm recalibrated,which is $150.00.

 

You talking to me? Im confused.
