I have a 1995 Acura Integra that has a bit of a hesitation issue. I would push the accelerator down about half way and I would keep pushing down and see no response in the rpms. Eventually I would hit a spot on the accelerator closer to the floor where the rpms kick in, but there is this big dead spot where there is little to on response. I will also throw in that the rpms fluctuate sometimes on a cold start. No air in the cooling system wither. Since it is a 20 year old car, and in the 2 years I have owned it, I have not replaced the tps. Does this sound like symptoms of a worn out tps? I’d appreciate the feedback 😉

Thanks for the feedback 🙂 Yeah, I did that and I also installed a new kick down cable and adjusted that as well. It has always had this characteristic before the new kick down. I do wonder if the fluctuation and the hesitation are 2 symptoms of the same problem.
I’m going to be more specific on the hesitation. It hesitates in 1st gear more than anything, especially at operating temperature. It could be that I’m running too rich or lean, but I just rebuilt this b18b1 engine. It was an issue before. Better after the rebuild. Oh and that fluctuation was just the FITV that needed to be cleaned.
A vacuum leak on the intake manifold side of things can cause a problem like this and so can an air leak on the intake tract side of it between the throttle body and air cleaner housing.
Another possibility could be a timing problem. That could mean if the cam is not lined up right from a timing belt job or if the distributor ignition timing is not correct. Retarded timing can cause an engine to bog.
I do not hear any hissing on the intake side. I’ll still inspect the hoses connecting to the intake. The intake manifold and throttle body gaskets are new. It is very possible that the timing is off a notch. The belt was recently replaced and might have stretched itself out a bit and broke itself in. Thanks for the info 🙂
