89 Vert
#1
i recentky put my rebuilt engine in my car it turns on real quick if you put the foot on the, gas it doesn't turn on by itself like it should.But even when you turn it on it doesn't idle you have to leave the foot on the gas then it stays on around 2000 rpm with the foot on the gas still then it starts to rev up from 2000 to 2600 rpm continously.(up and down)but if let go of the gas it shuts down, any of you guys have an idea why is doing that?as far as i know i have all the vacuums etc. all hooked up.any help will be greatly appreciated,thanks.

First, turn down that idle. My idle was at 1,500 and bobbed up and down because that's too high, it just is. My brother loosened my throttle cable and it sat RIGHT at 1,000, NO problems. If just lowering the idle doesn't fix it, then check your TPS.
When you first start the car, keep it revved to about 2,000 with your foot for about 15 seconds or so, then just let it go and let it adjust on it's own. That helps to warm it up for just a second, and then just let it sit there till you SEE the temp gauge move, then you're ready to drive.

could you tell me what the tps is or afm is or where can i find it or maybe where i can find an illustration of the parts involved with the intake system,as you can tell i'm not familiar with these parts.

I belive the TPS (Throttle-Position Sensor) is that big plug that's behind your alternator when you take the intercooler off. If you take it to a shop, they can check it's continuity.
I got mine running again, and I thought the idle was too high cause it sat at 1,500rpm after I had a bitch of a time getting her started. I shouldn't have messed with it though, cause it was perfect BEFORE it died, so why would it have changed...
Then the idle was too low, like 650-750 and it wanted to die alot, and was very unstable. I turned it up later to 950 and it's perfect.
Still having trouble keeping the idle steady when i first start her up, but as soon I just let it warm up and then start moving, I'm in good shape.

ok now youve prob confused him a lot bc he doesnt have an ic. 89 vert= no turbo. hey man dont worry about taking your intercooler off bc you dont have one. hes probably got that thing all taken apart now to find the intercooler. there is a factory service manual online at iluvmyrx7.com
