All of a sudden my check engine light goes on... and the Toruble code in P0171? Also my engine sounds a bit moreraspy evertime I hit the throttle.... WHat could it be and is it bad? Im running DOugs 93 race tune on a C&L Racer CAI

Running lean on one of the cylinder banks. Contact Doug.

In the meantime make sure the intake is on secure without any leaks. You probably have a P0171 and a P0174, meaning both banks are running lean. I had these codes when I recently installed my delete plates and a Bamachips race tune. The problem ended up being that Doug accidentally sent me a tune written for a C&L Racer, and I have a C&L Street.

Roger that... Thanks... will it cause more damage if I still run it like that? Or better yet, whats the worse that can happen... Im a bit worried about it... Thanks

I was worried about it too, I ran mine for a few days with the wrong tune. I asked Doug if I could have caused any damage, and he said that it was fine. My car seemed like it was running fine. I would still get it fixed as soon as you can. I would recommend trying to drive it as little as possible, but if you must drive it take it easy and baby it.

 

Lucky for me its winter here so the car is not being used but i have ran it for the past 2 days.... Thanks for the help... I was really worried that my engine had to come out...
