i have a ls/vt tech del sol boosted i got it tuned at evans tuning who is the **** by the way, anyway the car ran its ***** off when i got it back then about one to two weeks later it just started running like crap, a/f are off at idle and partial throttle, it starts when the car warms up, jeff sent me a revise but didnt work can anyone point me in the right direction of where to look im out of ideas thanks

 

Have you done the usual checks? Fuel, oil pressure, Ignition? If not on the mechanical side, is the computer still operating properly?

 

checked all that and the computer is running fine, i was leaning towards a vac leak but ive cheked them to and im just out of ideas of what to look at now

 

Try reading your plugs to get an idea of what's going on.

 

have you checked plugs? replace them? check cap and rotor?

 

The plugs are white in cylinders 4/3 the other two look to be burning properly

 

Where is it white at. Can you photo it for us? White can be Incorrect spark plug (too hot heat range), Low octane fuel, Timing is not set properly, Cooling problems, no or low coolant, low or no engine oil).

 

what injectors are in ur car?

 

I got id1000 injectors, my plugs are bkr7es11, there white on the top of the metal facing the cylinder

 

ok well the car seems to run ok for a short bit then back to its old ways of running like crap, now shes running pig rich (10) on the af gauge while in boost and real lean at idle on partial throttle again so im lost again
