2000 Jimmy V6 Running Rich...?! Need Advice.

Recommended Posts

Well I just bought a 2000 GMC Jimmy 4.3L V6 and it throws two OBD codes:

 

P0172 Bank 1 running rich

P0175 Bank 2 running rich

 

I googled for it, it could be some clogged injectors but the idle is perfect and there is no lack of power. I went to the GM dealership they told me it could be the MAF but finding out the real problem could cost some $$$ and a MAF alone is 284$.

 

Anyone else had the problem? I put some Injector cleaner in the tank but it did nothing except that the light doesnt stay on all the time but goes off from time to time.

 

I believe the light comes on once the engine is hot.

 

Any advice would be appreciated. Thanks!

Clean the MAF and see if that solves the problem. The only other problem I can think of is the FPR or the spider is bad.

 

Did you not check the vehicle over before you bought it?

Well I looked at the maf, it looks clean, the sensors aren't dirty neither is that screen. I cleaned the air filter. It was not dirty, too.

I knew about the codes when I bought the car, I got it cheaper therefore.
