I just completed a pi swap on my 98 gt. Besides the swap, the only other addition to the car is a bbk cai. The problem is, when i first started it up, it idled and ran fine for about 5 minutes. After that, it idled terrible, acted like it was running on half the cylinders or something. The engine light is not coming on either. My concern is it jumped time somehow, is this possible. Any help would sure be appreciated......thanks

 

just want to add that i have the sct x3 with custom tune. it does have a trouble code the the car, it is p0353.......does anyone know what this is or where i can go to find out......thanks

 

P0353 Ignition Coil C Primary circuit fault. Check your coils and/or the wiring.

 

well i checked my coils and wiring.....then cleared the codes and and started car again. so far its running smoothly......another issue is that it idles around 1500 rpm....im a newbie to this, can i adjust the idle with the tuner?? thanks for your help

 

Sound like it may have been just a bad connection then.

As far as the idle goes. Unplug the IAC (idle air control). Start the car and adjust the idle screw till you can get the car to idle at the lowest rpm as possible. Shut the car down and plug in the IAC back in. See if that helps.

 

That would cause the car to run rough. There ya go.

You can adjust the idle through your tuner if the user options are installed allowing you to modify different paramaters of the tune. Not sure how the new tuners are but my xcal 2 asks me when I go to install a tune if I want to modify the tune paramaters. At that point I go in and adjust what I want.

 

well i cleaned the idle air control and was able to adjust the idle speed with the tuner. so the far the engine runs smooth.....after the pi swap, i can definately feel the increase in power.....thanks for all the help
