thanks

 

did you set the timing back to stock after replacing the dizzy?

 

Try replacing the fuel filter too....

 

both are good suggestions to try out. what computer are you using and what is your timing at ? also on an older engine check that your injectors arent clogged. also is your head ground in the right spot ?

 

I am running a PR3 man. ecu. I have not been able to check timing yet, need to get a timing light. replacing the fuel filter was the next thing to change. I will need to check that my injectors are not clogged, I know that some of the o-rings on them need to be relpaced. any other sug.???
