Please can somebody post a pic of the air bleed adjustment screw , i really need to sort out my idle hunting problems i have read through 100's of posts and today adjusted my tps to the correct settings.
But still no joy here's what happens when i start the car up cold idle is ok as soon as i drive it a little and then put it back into neutral idle is hunting as soon as i put it back into gear idle is fine although it has always has seemed a little high.
I have a picture of the proper idle bleed screw near the elbow but haven't adjusted this yet , but i haven't got a clue where the air bleed screw is ? a pic would be excellent.
Also i have read that it could be a throttle plate stuck any info on this would be much apree.

Thanks very much is that the only one then the main one , because i have heard people talk of an air bleed screw and an idle bleed screw are they the same thing mate?.

If you just want to change the idle, don't mess with the other one. Just adjust the one mentioned above. Turn it clockwise to lower the idle, counterclock wise to raise.

Sorry to bring this back, but I just bought a used replacement tb with tps.

I'm having problems starting the car, but once it turns over it's fine. Have to give it alot of gas and cranking. Will this help with that problem?

have you removed your ISC? that's there to improve cold starts

Ohh yes I have. Is there any way to improve start ups with this out?

I have problems with hot and cold starts.

I have problems with hot and cold starts. If I put the ISC back in, it would clear my problems?

i mean it would probably help, but I can't guarantee anything as I don't have the car in front of me and there could be something else going on. You can see from the FSM pinout that the ISC valve opens at full duty during cranking to improve startups:



Do yourself a favor and clean it before you put it back on. Spray some carb cleaner in there and apply 12 volts across the terminals multiple times.

Thank you very much! With the ISC back in, the car turns over much easier.

However, sometimes it'll start immediately right up. Others it'll crank, crank, crank, and crank with the gas pumping to get it to turn over. It's better, but not completely fixed.

Is there something else I can do to improve startups?
