loominaz34 Posted June 30, 2005 Report Share Posted June 30, 2005 hey guys, my car's unhappy. the problem is that the car sputters and hesitates horrendously under anything past 2% throttle anywhere on the tach.though sometimes I get these spurts of full power the on occasion makes the tires chirp. Also, idle might be a touch rough. the plugs are new as of 300 miles ago and the wires are good. I dont know how to check the coils. thanks for the advice.

chadz34 Posted June 30, 2005 Report Share Posted June 30, 2005 Yeah, possibly coils or fuel injectors. Quote Link to comment Share on other sites More sharing options...

89SupremeCutty Posted July 1, 2005 Report Share Posted July 1, 2005 Check your EGR valve to see if it's moving when you rev the engine. It should not do anything in park or neutral. Quote Link to comment Share on other sites More sharing options...

JMo60 Posted July 3, 2005 Report Share Posted July 3, 2005 check fuel pressure at the rail, you could have a bad fuel pump or plugged fuel filter Quote Link to comment Share on other sites More sharing options...
