hey guys, been a long time!

Finally getting around to getting my car back out, it's sat on and off for 2 yrs due to getting married, buying a house, etc etc.. that old jazz song.

Anyways through out the past 2 yrs the few times I've driven the car i've knoticed that when it's cold it bounces the idel something fierce for like 10 secs then it mellows out. Not a big deal i can deal with that... but my main problem is that once it hits 150*F coolant wise Everything goes F***ing haywire!
It wont idle it'll just sit there and surge up and down till it either mellows out eventually or it falls flat on its face. It does it while im sitting at stoplights or just even letting it warm up in the driveway.

Checked all my charge piping everything is tight, Cleaned the MAF and TB real good and still does it. the only thing I've knoticed that helps remedy the situation some is if I turn on my A/C... but thats like a 75% chance of it idling fine.

Any thoughts??

It's a complete hahn swap, nothing more. never really had a chance to play after I did it.

 

low pulse width coupled with dirty injectors, problem found.

clean injectors.

 

Any particular Injector cleaner suggested?
I ran Stabil Ethenol through it and it only helped but very little.

Could the tune have anything to do with it? cause it never really did run right when i first swapped it.

 

Using the street race int mani? Did you use a new int mani gasket? Or silicone on the old? Please find a tuner asap.
