okay my car was running fine until the other night all the sudden it started missing at high rpms especially at WOT.

* car starts perfectly
* car idles perfectly
* can rev to redline in neutral no problem

when driving i do get some minor missfires at low rpm. at about 3 or 4k if i am at WOT it will stop revving and missfire like crazzy. if my foot is not so heavy i can raise it pretty high through the rpm band with no missfire.

REPLACED-
distributor
spark plugs
spark plug wires

thanks in advance. for any info / ideas. like i say it was running perfectly a few days ago

 

kailua huh i used to live in kaneohe! anyway hows ur timing?and any cel?

 

no cel. i assume my timing is still good. i need to double check that with a light though. i did look at my ditributor bolts and it had not moved, and when changing it i set the new one right in the middle where it should be.

 

bump - i think its my fuel pump i will replace it tonight with a stock one and also check timing. i have a really bad feeling when i purchased my walbro from ebay i got a knock off >.<
