Hey all, i am having a problem and could really use some help. At around 2500 rpm or at 10% throttle im having a moderate stutter issue with the car. It is only throwing one code, and that is for the cruise control switch. Does fine under half, full, or no load. Any ideas on what this could be? I also noticed the tac sticks at 2000 rpm for about a tenth of a second when returning to idle. I am about to have it in the shop for a new clutch setup, and would love to be able to tell them what to fix for the stutter issue. Any help is much appreciated. Have a great day!

 

any mods? tune?

 

No completely stock, sorry should have said that. it just turned 30,000 miles.

 

Hmmm. I had a similar stutter but it was just a few spots in my tune that had to be worked out a little better. Not sure man, hope you figure it out though!

 

Only stutter I ever had was due to intake pipes clamps had loosened around throttle bodies. Check all your clamps. Could be a lot of things. Sensor issue of some sort. Goto Autozone or someplace and scan it. See what SES/CEL you have.

 

Yeah that sounds like a small air leak issue or something similar.

Quick question, what oil is in the car and how fresh is it? I had an issue with a Z using heavier oil that had a funny VVT issue until it warmed up, went away when we went back to a regular weight oil. Only showed up at very light throttle like you said and it wasn't much of an issue but it was there.

 

Just had oil changed, used 5w30 synthetic. Checked all hoses, no vacuum leaks. Still only throwing cruise control switch code. But cruise still works on my car. It looks like its more throttle position than rpm as i can get it in multiple gears at dif rpm but always at 10% throttle. Its getting a new clutch wed so ill have them take a look at it. Will inform you all after problem is diagnosed. And another ? Gonna put a cluthmaster FX 350 clutch and flywheel in my car. All ive heard is good but anyone with any first hand xp on it.
