Okay, I just switched out my radiator and put in a OEM designed one. I poured new fluid in and let the car run for about 10-15 mins and I didnt notice a single problem. I decided to actually go and road test it so I could see if the car stayed cool and what not.

After getting about 1.5-2 miles my car just died. It wouldnt start back up and it was getting a spark so we thought it might be the fuel pump. After a day we went back and it started up first try. We check fuel pressure and looked normal

The problems now are

-- In Park and Neutral the car idles at about 1500 opposed to the usual 900-1000 and its pretty rough
-- When I put it into reverse, drive, od, ect. the entire car jumps and rpms go back down to normal levels but car still runs rough.

Ive checked if I missed a wire or hose that I took off during the radiator change but I cant find a thing

Thanks to anyone who can help

 

Vacuum leak, spray around with carb cleaner till you hear the motor change RPMs. Track the leak down from there. It normal for a car that is idleing to high to jump when put in gear.

 

Yep what he said ^ :P or a disconnected sensor

 

Just be careful where you spray the carb cleaner. It's made to remove varnish on a carb, but it also loosens paint.

 

okay we ran the trouble codes and it ended up being the throttle body control sensor. and it was running at around 6volts.
everything is fixed now =]

 

yea, that happens to mine. its the dang sensor. i have to unplug it then turn it off, plug it back in, then turn the car on.lol i guess its dirty or something.

 

I've got a dumb question...
I have been having Idling problems, about every other time the car starts it will idle to high, and the check engine light will come on... Then about 3 to 10 minutes later(pretty random) it will go off, and the car will idle and run normal. I don't think it is a vacuum leak because the problem is only once in a while. So I think it's the Thottle body sensor. How do you check the voltage and adjust the sensor?

 

Your chilton should tell you the right range fo your car an model. It's the throttle position sensor and should be checked by reading the ohms. I've never checked using voltage.
