yeah i was thinking that going stock on the pullie might be a good idea for now.

i will be doing fuel tests and ill get a new Fuel filter just to be safe.

As for the HB i realy think its the right one, the motor idles just fine if you ask me, ill get a vid tomorrow (no cam today )

Read this thread, even though it'* long:

The end result ended up being the harmonic balancer. Don't discount the idea of it NOT being the HB.

I read that whole thing, what you describe isnt quite like what im having, yours idles liks ****, mine idles fine, it just has no balls when it gets warm/hot.

heres a list of whats been done since the issue first happend last april.

things i havent changed

Do you have any pictures of the new/old balancers? I'm primarily interested in the positioning of the holes that hold the rings onto the balancer in relation to the keyway. If they are identical then this shouldn't be a balancer issue, the only problem balancer related may be a vibration (and you say there isn't one). That should solve our questions of balancers and move us onto the next stage of diagnosing.

When the engine harness was swapped over, you would have repaired any bare wires or rubbed spots. Therefore we "should" be able to rule that out.

The crank sensor.. while it appears to be performing..my own experience with one leads me to have a feeling it could be a good suspect. Especially since your issue only occurs when warmed up. Something is expanding/shorting/rubbing/doing something..to cause an issue.

PCM... heck, it sure could be a possibility. Although I believe Don would have been all over it already if it was exhibiting normal failure symptoms.

Maf...you cleaned it when you had everything apart and it'* known, try unplugging it and run the engine that way. It'll set a code, but how does the car run under the same conditions that exist when the issue is noticed.

I dont have any pics for comparison of the HB'* (new one was perchased/installed while i was at work)

when i did the swap, I didnt go over the harness with a fine tooth comb, but i did look i over and fix thing like tape drying/coming off and what not.


the Crank sensor I will have to take into serious thought on replacing...would a used one be good (being sure it was from a 92) I really cant see why not, considering every one is runnign on a used one if you think about it.


As for the MAF, are you saying drive it till the problem starts, then cover the sensor with something (like tape?) then see what happens?

just unplug the MAF, you can drive around with out it and see if you still have the problem, thats what i did once to try to find one of my problems.
The PCM will run on a Default setting while it not plugged in.

now why didnt i think about that?

i didn't know either until someone told me

To clarify (I know what he meant.) you can not drive around with your maf "out". You can drive and the engine will run with the maf unplugged.

heres a cell-cam vid of the motor at idle (suund seans a little off from that it acctually is)
