Clogged fuel filter and there was a muddy substance in gas tank. Jag guy said that the problem is recent but I am going to get the mud checked to see if it is from Florida (where vehicle came from) and if it is then it was an existing problem and the car dealer will probably take care of it. If the substance is not dirt then I'm pretty much screwed.
FJT, the reason we were off is because it pop two new codes when they had the vehicle.

 

Well the check engine light is back and the Restricted Performance, same frakin codes P0171 and P0174.

 

What is long and short term fuel trims when car is under a load? Possible mass air flow meter.

 

Dont have a minimal idea on how to check that.

 

need to hook up to scan tool and read them. If they go to 20% or so mass air meter bad. -20% I mean

 

Well then I will see and report back to you

 

good luck

 

Well haven't had a chance to go get it checked out but the check engine light turned off and the Restricted Performance as well, has been two days so far and no Check Engine Light.... what you think.

 

Still look at the fuel trims.

 

Well I talk to the dealer that sold me the car and told him what happened (he was out of town), he is going to call the mechanic to go ahead and check the car once again. I will tell them to read the fuel trim levels to me so I can report back to you.

 

Make sure you check them under load. From stand still under acceleration.

 

Well found out it was th right cat
