my fourth gen prelude is misfiring. . its wierd because it only happensin the low rpm and when it hits about 3000 rmp its fine. ex: at idle its fine then when i give it gas it hesitates, then after 3000 rpm its fine. . it only happens when i start to accelerate. . the car is manual 2.2 vtec. if anyone has a clue as to what is goin on let me know thanks

my 2.3 is doing the same, i was told its the distributor, im going to buy one this weekend, i hope it works

i also thought it was the distibutor. . so i changed it and it still kept doing it. . its not the distributor. . my friend tells me its the throttle positioning sensor (tps) so im going to try and replace that this week. . see what happens.

That's most likely the problem, if not... good luck, this low RPM range hesitation issue has stumped dozens of people

when i first got my prelude mine was doing the same thing.. i got new plugs and a cap n rotor... worked beautifuly after that.. start with those cause a dizzy can get expensive.. start with the cheap stuff then go bigger

so i changed the tps sensor and it did the trick. .it took me about a year to finally figure out the problem.. now i have a piece of mind

What Your Check Engine Light On Before You Changed The Tps?

My japanese import BB4 does this, but not all the time.
It seems to only do it once warmed as it never does it when cold.
New plugs, cap, etc have been fitted and still the same.

Forgot to add that it clears once the vtec opens up.
