I recently had a problem where the car would run perfect for a good 20-25 minutes, then the idle would start to drop, temps would go up, and the car would eventually shut off.... got that situation all fixed today and now i have a new problem... the car runs fine temps never went over 88, and about 25 minutes after driving it, it starts to idle really hard. It almost sounds like the engine or tranny is shaking, kind of like a squeaky noise its idling so hard. I attatched 2 videos from my cell phone if you cant hear just forget about it lol... but any ideas on what could be causing this problem? I take my car in oct 12th for tuning and want to have the car running perfect for it. thx.

I smell a ls1 in your future. No more zoom zoom more like vroom vroom

 

the problem is you have no pistons. you need at least 8.....with ohv.......and a polymer intake manifold........with a t56..

^he got it right needs an ls1! lol

 

oh shit, is that what i need? I wasnt sure

 

Not really sure whats goin on based on those videos.

I mean, it sounds like you have a ported motor (although I don't see that on your mods list...)

When you say it idles "hard" are you just refering to the shaking? or are the rpm's fluxuating as well?

 

Stock port. And when it idles hard its shaking making some kind of metal against metal noise, and the rpm's fluxuate. Happened again lastnight

 

Time for fluid checks.
oil?
Trans?
Diff?
try running premix and see if it makes a difference

Also, what was the cause of that first problem you talked about? and how did you go about fixing it?

 

Don't get an LS1 unless you want 90/10 weight distribution. Buy my package and fix all!
