douellette Posted June 30, 2009 Report Share Posted June 30, 2009 when i accelerate using 50% or more throttle, my car seems to surge or loose a little bit of power off and on again. what could that be? its a 97 cutlass with a 3100. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted July 1, 2009 Report Share Posted July 1, 2009 Could be a missfire. Quote Link to comment Share on other sites More sharing options...
douellette Posted July 1, 2009 Author Report Share Posted July 1, 2009 well the check engine light is on and i scanned it and it said cyl. 1 misfire. but the plugs and wires are new, and the coil had about 6k ohms resistance...same as one of the new coils on it. so i don't know what else it could be?

ManicMechanic Posted July 1, 2009 Report Share Posted July 1, 2009 ICM is a possibility. Quote Link to comment Share on other sites More sharing options...

douellette Posted July 1, 2009 Author Report Share Posted July 1, 2009 ICM is a possibility. is that "idle control motor"? but it does it when its not idling, that thing is only used when the car is idling. Quote Link to comment Share on other sites More sharing options...
douellette Posted July 1, 2009 Author Report Share Posted July 1, 2009 ICM, injector... i put two bottles of fuel injector cleaner through the tank, doesn't seem to make a diff. Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted July 1, 2009 Report Share Posted July 1, 2009 Ignition Control Module. What the coils are mounted to. Quote Link to comment Share on other sites More sharing options...
douellette Posted July 1, 2009 Author Report Share Posted July 1, 2009 Ignition Control Module. What the coils are mounted to. but those are expensive......... lol Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted July 1, 2009 Report Share Posted July 1, 2009 I have about 5 spares in my garage if you need one. And if those bottles of injector cleaner dont make a difference, it means your fuel system is clean and running good. dont put more in. Those burn HOT.

ManicMechanic Posted July 1, 2009 Report Share Posted July 1, 2009 lol, true enough. But if there's one close by, most auto parts stores can test them. They will need to run the tests multiple times in a row to check if it's bad. Or you could try getting a good used one from a junkyard.

jman093 Posted July 1, 2009 Report Share Posted July 1, 2009 A leaking intake can also cause that. It sucks air, basically a vacuum leak for that cylinder and it lean misfires. Quote Link to comment Share on other sites More sharing options...
