have any of you tried this? how hard or easy is it to do this kind of job on a 91 integra with 243K on the odometer. this car underwent a major tune up andtiming belt replacement. it runs better than it does when i first got it now but there is still that hesitation when i slow down and then go or when i downshift. my mechanic said it might be the injectors are clogged up and need to be cleaned. any comments or suggestions?

 

what engine is it?

 

things to look at or have checked.





slop in the throttle body (butterfly plate)

weak fuel pressures

vacume leaks

temp sender out of range

worn out engine mounts can cause a hesitation, but usually with a big thump sound following.

 

more than likely that car has a b18a1 engine. over the next few gas tanks put some fuel injector cleaner in your tank. That helped out my car whenI first bought it.
