Hey guys so recently my ignitor went on my car, causing it to shut off as soon as the car got hot and wouldn't be able to start the car after it does till it cooled down.

went down to the pick n pull and grabbed a spare dizzy and tossed her in, drives perfectly fine now but i have noticed that when the car warms up, and when i come to a stop she idles really rough probably ranging from 300-500rpms till i apply throttle, than she will idle high (1200-1400) for about a minute and than go back down to the low idle (300-500).

Im just wondering on were i can start looking, i have already cleaned the IAVC with no luck.

I have also noticed my boost gauge doesn't ALWAYS read -19vac at idle, sometimes she's closer to -12vac.

Possibly a vacuum leak?? any help would be great thanks!

 

u need to set the timing if u replaced the dizzy.

u cant just throw in a dizzy and be done lol.

u gotta set the timing n it should clear up ur idle

 

^This, set the the dizzy rotor to be pointing at the correct cylinder when it's at TDC on that cylinder. Also, make sure you didn't knock any vac lines off.

 

I did set my timing when I replaced the dizzy.
Is it possible I ****ed up and that's what's causing my problem?

 

you cant have messed up the dizzy, it only goes in one way and since you already did the timing. check to see if you have a vacuum leak

 

sometimes the timing does jump a tooth or two either way. might wanan double check

 

alright ill do this tomorrow when it stoops raining outside (wish i had a garage )
i will also try and check for leaks if that is not the problem. thanks!
