Today I was idling at a LONG light and I noticed the idle being really low and the car was shacking slightly, and the oil pressure was at the 20 dash. Is that kinda low?

What could this be? I just put in Fuel System Cleaner on this tank. My engine temp was at like 180-200. I have 3/4 tank of fuel.

What could be going on?
How do I fix it?


Thanks, Any help is greatly appreciate

 

What rpm is it idleing at? 20lbs isn't low at all for idle, mine goes slightly below that sometimes.

Also, I highly doubt you're making anywhere near 390hp with the mods you have listed in your web page.

 

Im getting there...lol

It idles at like 600-700 in PARK

It idles at like 500 in Gear

 

I don't wanna sound like a dumba$$ or anything buts whats a B4C? Thought I knew most of my stuff on Z's.

 

Well, I don't have an automatic, but that doesn't sound like it's dangerously low. As long as you're not having any other probs, I wouldn't even worry about it. If you want some added assurance though, remove your IAC and give it a good cleaning. I removed my throttle body, and cleaned the butterflies, IAC and it's port, and got tons of gunk out of it. Seemed to help my idle out some, and gave me peace of mind knowing I got 10 years of crap cleaned out of it.

 

B4C was the police package. Not exactly sure what it entails, but I've heard larger alternator, and heavier duty shocks.

 

Ahh...I'll have to look into that
