Question about Chevrolet Suburban 1500
I have a 1987 cavalier that idles excessively high. it will not idle back down until I am at a complete stop and even then it seems high to me. Also under normal depression of the gas pedal on acceleration I get a stutter and backfire through the TBI all the way to the breather element.
I replaced the AIC in hopes that was the problem but it did not fix a thing.
Will a MAP or TPS do this ?
I have cleaned the injector, as well as the port in the TBI leading to the injector that is what I assume to be coming from the pulsator regulator diaphram or some thing like that ?
Any insight woul dbe appreciated. This is unfortunately, my daily driver for now so I need her in tip top again fast for work.
Thank you !
