when im driving, hot or cold, in any gear, above 3k rpm i get misfires and my tach jumps all over. car is a 91 civic with a mini me swap on the 1.5 b2 block. computer hasnt thrown any codes since i cleared it a day ago. before that it was flashing 1 and 9. before this the car died on the street and threw a code 15. i cleaned off the terminals for the coil and the problem seemed to go away. now its back after i hit some bumps. im thinkin loose connection, fuel filter, or coil. any other suggestions?

 

Sounds like the Distributor is fucked. THats exactly what happened when mine went out. It wouldnt go past 4k. Right when it got to 4k, the needle would jump around and the car would sputter. Youll need a new Dist.

 

alright. thats the best scenario because i got another dist. sitting in my room and as soon as i get my conversion harness back the problem should be solved or changed. how long do you think i have until my distributor doesnt work at all. im gonna squeeze every last drop of life from it.

 

thats up to the distributor. it might be dead right now, or it might last for another 3 months. you never know

I agree. As soon as i got that prob i changed it right away, you never kno, it might go out when ur 50 miles from home

 

If the ground at the thermostat is loose it will cause the same symptoms.

check for those loose rotors in the dizzy...very common.....stupid screw always getting loose.....happened to my *** all the time....

 

jumpin idle usually means the ignitor is out......from my friend eric told me yesterday....

 

this happend to me.......... check the connections on the ignitor....... mine were corroded and somewhat loose.......... i cleaned em up and crimped em down on the terminals and no more of hesistation or crazy tach......... please try this before you buy a distributor!!!!!

 

if it an ignitor hit me up.....

 

like sloorex said, check the connections in the distributor, they have been known to come loose.

 

most likely the ignitor or coil but i'd guess ignitor since they're much more common.

 

i sorta got teh same probem with my si only mine doesnt misfire sometimes the tach just goeas crazy above 4k and will pause for a sec the jump like 5 or 6 hundred rpm but the car runs fine whats that about?

 

yea i re connected the wires in to the ignitor and the car ran tha same. then one morning it ran perfect for a few days until i hit a nasty bump. now its back. im pretty sure its a loose connection on the coil since ive got it ghetto rigged. well see when i convert to obd1 finally

definitely a loose connection....... same thing happend to me when i went over some railroad tracks......... 1 main terminal popped loose and my whole car sputtered and shut off......... popped my cap of and re-tightened it and i was off.........

im glad i always have my tool box with me.......

 

Same thing happened to me and it ended up being the Cap&Rotor. Hope this helps

 

I've had the same problem in my 90 DX (stock), cannot figure it out. I've put in 2 distributors now, ignitor is new, coil is new, no loose wires, ground @ thermostat is fine, all other grounds good, car doesn't miss though. I thought I figured it out one day when my friend tapped the starter with the power on and the tach jumped, changed that ground and still have the same problem. I pulled the starter and cleaned the trans case to ensure a good ground. The SI cluster is fine and the dash grounds are good..... ECU??

 

its the ignitor. the problem can be caused by not just a loose connection at the terminals, but also internally. replace the ignitor (with honda oem), the problem will go away. how do i know? i just had the same problems and replaced the ignitor from my spare disitrbutor and its all good now.
