[boostedhatch]

I got the silver spirit running to day and i have around 17-19 pounds of vac idols at 900.When i first start the car it runs rough then it start to run alot better i checked the codes and it saying one of coil drives are bad.Can that be the reason my car is not wanting to take boost.Other then that happening the car runs great any ideals?

Anyone

Change out the coil, you got a spare? Also, check the wires/plugs. How long was it sitting?

[boostedhatch]

yup changed coil/plugs/wires/fuel filter

[Will Martin]

Did you have the code BEFORE you changed the coil? If so, you got another computer to try?

[boostedhatch]

yup

If one of your coil drivers is bad, the engine will run terrible. It will have a very pronounced misfire which will cause poor performance and low boost. Normally the computer is the last to suspect for issues, but if you have changed out the coil pack with a known good unit and still have problems, that may be your problem. Check your coil circuit wiring COMPLETELY with a multimeter. Check for resistance and voltage. Check all of your connections too.

If you don't have a bad misfire, I don't know what to tell you.

I do have a bad misfire. I changed coil's with another one and I had no ideal if it's good or not.Is there anyone in ohio that has a good one I could try?

This is what advance auto parts said that the coil is interchangeable with is this true?

Okay i was messing with the spirit today and the car runs good after the coil fixes itself and i give it gas and it hesitates and struggles to go over 3k rpm but if you tap the gas over and over again the rpm will go higher but as soon as you put it to the floor it will start to break up and wont go any higher in rpm could it be tps? still no codes

[boostedhatch]

Anyone.?I was thinking i went from a 4 wire o2 to a 3 wire.I needed a quick fix so I installed a 3 wire could that be a problem? The only codes are 15 and 43

[boostedhatch]

Ok tried 4 wire o2 no change. I grabed the tps and the idel changed so I think I need to tighten it up.Is the a proper way to put the tps on?. Are all the tps the same for our cars.Another thing is that while I was checking the tps the coil shocked the snit out of me.Any reason it shocked me without me messing with it just laid my arm up against it.Really need some advice on how to get the car running alot better so I can drive this car

[movaldes]

sounds to me like the coil is cracked or one of the boots on the plug wires is cracked...

[boostedhatch]

i'll check

[boostedhatch]

Ok check the injectors and they were spraying out like a water hose.So I changed injectors and runs great cant wait until i can drive the car for along distance wow
