moved to 2g section so you can get more responses

 

Check Your distributor, something might be preventing it from firing at higher rpms.

 

Are you sure you dont have it timed 180 deg out? Sounds like it is out of time/or 180 out..

 

There isn't a dist on 420a.

Did you check your base timing w/ a timing light? Just double check everything you replaced and make sure everything is plugged in and you dont have any missing vacuum hoses.

Is therea cel?

 

I missed the fact that it was an esi Glad you pointed that out

 

lol I did the same thing.

 

You should also check your fuel pressure when it starts to missfire, it could be a fuel issue.

 

k yea i will try cause it started all when the timing belt went yess i was 1 of the .1 % that didnt smash the valves into the piston after it was the exaust cam that jumped but if it was fuel wouldt it do it when the cam sen. was unpluged to cause tats the only way i can even drive it it can give u wipwash

 

So, you fixed the problem or no?
