Rough Idle And Stalling Prob At Slow Speeds Clutch In

[juls33]

a little help on the adjust ment for the series two TPS

their are two connectors which one does what

i know the values for the signal wire are 4v - 0.6 var 3.0

which connector do i check

thanxs

signal wire is the middle wire of the bottom connector

should read 0.6v at idle and 4.0v wot with ignition on

set to these values and clutch in stutters are no more

It's the middle wire, i did mine by adjusting so that when i blimped the throttle i got instant response, otherwise to much and it will be slow, to little and to slow, mine is 0.39V at the moment.

It is suppose to be about 0.4V but manual states up to 0.6V

Vacuum leaks will cause a similar issue.

So can:

*Faulty water temp sensors.

*Faulty 02 sensors (although this is debatable because some people say this only affects the open looped maps, but many people have complained of poor idling performance with this faulty sensor.

*Faulty AFM

*Non-recirculating BOV's.

*Faulty AAC valve

*Faulty Idle bypass valve

*Faulty Cold start valve

*Faulty computer

*Faulty wiring

*Excess carbon buildup in the intake plenum/AAC valve/Coldstart valve/throttle body.

*Faulty fuel pump

*Faulty fuel regulator

*Faulty idle circuit for fuel pump to run (at idle)

*Clogged fuel pump/sleeve/poor fuel.

The list goes on...

I had a stuffed up idle plus hunting and yep tps was the problem.

[Danny Mack]

hey i have the same problems and also when car is in neutral (whilst driving down a hill).

what is tps where and how do i check/ change settings???

Why do you have your car in neutral when you're driving down a hill?

The tps is attached to the throttle plate. Its a little black box with wires coming into it from the right. It can be adjusted using two bolts holding it to the throttle plate body.

The correct values for an r33 are around 0.4v for idle (closed throttle) through to around 4~4.5v for WOT.
