this car is getting on my last nerve.. nothing has gone right that i've had done yet, anyways to the point here..

The car is running like.. well crap. im not sure what exactly the deal is but its definately something wrong on the left bank, (true dual exhuast and i can tell a HUGE difference justplacing my hand from side to side, feels like two cylinders down but definately one both on the left bank) i checked under the hood the spark plugs appear to be ok, and also checked later on that night for arcing and didnt see any (but may be something loose as one of the plug wires on the right bank was completely OFF when i got the car back )

anyone got any advice as to what to check next? gonna take it back to the shop tomorrow but would like to get it fixed without the hassle of dropping it off =/

 

Well, first of all, you could say just what it was you had done to it so we have a clue. But assuming it had something to do with plugs & wires and two cylinders seem to not be making power, maybe they reversed the two wires.

 

ya know i hadnt even thought of them getting the wires mixed up.. bah, but all my mods aer in sig including what i just had done (or well maybe i already changed it to complete and mixed it in) anyways had a new engine (low miles lt1) put in along with headers and a 6spd
