is this a fuel delivery problem (done everything short of taking the gas tank out and getting it...."boiled?") or is this something like a CHT....it books from 0 to around 40...but...it's almost like the rings are shot, just no compression...i mean i can't even accelerate when going up a interstate hill....maybe it's just time to do all three.......

well if i unplug it, i believe it runs better than when its plugged in....cause i did that and it idled like its supposed to....when its plugged in, it idles at like 300RPM....its barely turning over...and the idle screw has ZERO effect on the idle....even if the TPS is unplugged. would the compression go to the hell in like 500 miles? b4 it was great, now this started. i think i might try a regulator cause its random enough to be the fix, yet easier than getting compression stuff done

I would check your timing and set it at 27 degress BTDC @3500 rpms with the hoses off and plugged. Then set your idle rpms.
Low idle like 300 rpms would indicate the timing is off to me for starters. |

Try using the lower speed power more effectively.

It would be help ohter readers if you gave info on your setup. which engine ? which fuel system etc ?
I suppose that if no info is given it makes sense to assume "stock everything", but a lot of people in the club have modified their cars. Hope you resolve your problem. Michel Richard |

That's great. I did 100mph in my lowered '63 karma ghia convertible w/built up 1600 engine and no factory supplied seat belts. I was young and dumb.... and lived to tell about it. |

Adjusting the fuel pressure would make a difference accross the range of power settings and rpm situations. You may want to rule out ignition stuff before looking at the injection. Are your plugs clean ? nice fat spark ? vaccuum advance working properly etc . . .

Did you change something before this occured? What was the last thing you touched before the problem started?
