My SRT is driving me crazy. Pls help!
My SRT is driving me crazy. Pls help!
So I finally finished my timing belt nightmare. The car now needs a radiator but I took it for a small drive last night to be sure that's all it needs.
Long story short. I gave it gas and had no boost. Then I tried again and all of a sudden it revved to 6k and wouldn't not stop so I shut the car off and coasted home. Everything appears to be connected so any ideas what I'm missing?
Ps. It had a new timing belt, water pump, tensioner, intake gasket, and a 2.0 cam installed if that helps give an idea of what all was taken apart.
Thank you!

Hmm, have you checked for vaac leaks? Was the intake gasket properly seated and bolted on right? That could cause major leaks..
I know when I tried it without a gasket on my 2.0 just to see what it would do, it rev'd like crazy.

Because a vacuum leak is the same as opening the throttle body. It is not the same as carburetted set up.
The only thing lacking is a proper TPS signal. The extra air means extra fuel, because the MAP and o2 sensor are telling the PCM the manifold vacuum is low, and the o2 says it is lean. So the PCM dumps more fuel to correct the problem. Thus it will rev as high as the air volume, or rev limiter will allow.
When My AIC solenoid stuck open, it easily revved to 4000 rpm with the throttle closed. It doesn't take a big hole.

Thanks for the explanation ... I guess I'll always think in terms of carburetorsoccasional demons wrote:Because a vacuum leak is the same as opening the throttle body. It is not the same as carburetted set up.
