I went out to eat last night and when I was done, I got back into my car and started it up. It didnt want to start so I gave it a little gas so it would start. It was running like it was missing. So this morning I went and got plugs for it, NGK R. I started it up agian and it is still doing the same thing. It seems like it wants to die at low idle, when it does idle my air / fuel is more rich than usual. It is puffing a little white smoke out the exhaust also. I checked the resistance of the wires and I got .22, .29, .29, and .33. If you can help please do I am going to the Indy Truck bash in 3 weeks. Thanks

 

list mods, ecu etc... and all stats

 

Small street port, stock twins set up in non-seq, dp, cb, stock ecu, 10 psi boost, manual boost controller

 

also the smoke smells like gas

 

check map sencor and all vac/hose lines something is disconnected...

 

checked all vacuum hoses, and map sensor, its hooked up

 

checked voltage on map sensor, i went from red lead to brown wire and black lead to black wire and got 4.95 volts, that was the highest i got when i tried all the combos

 

Check out resistance on leading coil

 

I think it is supposed to be 1 ohm. Anything .8 or less is bad.

 

Could the problem be idle air control valve. I started the car with the sensor hooked up and then un plugged it and nothing changed, so i plugged it back in and still nothing.
