It's odd when I start the car, sometimes, it will bounce from just under 500 to 750. When it's doing this, if I put it into gear it will die. It does it for a couple seconds then goes to normal idle.

It's not heat related because I started in mourning when it was cold, midday, night, and starts fine from place to place. It's random that it does it.

I'm just not sure what to check since I keep forgetting it's so rare (ya know how it is, happens when your busy and forget by the time you have time).

 

Check the neutral switch connector wiring on the side of the transmission and the clutch switch connector and wiring at the top of your clutch pedal. May be loose or intermittently shorting out.

 

How's your TPS?

 

I havn't checked it yet, I should of. I have the whole day tommorow to work on this and pulling my Monte's engine while me mums in hospital so I was hopin to get some idea's of what it could be so that I don't check everything and have half of it be useless lol

So TPS (looks like it's time to learn how to check that lol) & those wires (forgot its an auto but I assume there is still some sort of wire like that and no im not doing a 5spd swap yet my girl can't drive manual lol so until she gets a car im stuck)

 

There's two ways to check it. 1 is to use a voltmeter, the other to make a dual test light setup. it really depends on your preference. off the voltmeter you should get around 1v at any given time. and if you set it up using the dual lights, that's roughly what you get.

 

alright ty, lol that saves me the searching this site runs so slow for me
