ive got a real lumpy idle whe the car is cold, but if i rev it or drive it it's fine

 

any ideas :confused:

Not sure if the same prob mate but had a similar issue on mine when cold and the great andy duff set my base idle and tps today so fingers crossed it will be sorted.

 

cheers Paul

Hmm, mine is the other way around, smooth "on choke" a little lumpy when at running temp :confused:

Hi StellaZ,

There is another way of setting the TPS other than Consult. It involves testing the voltage by using a volt meter with fine probes and testing the voltage at the harness side of the connector. I will try and explain. Looking at the back of the harness connector (the one with three wires going in) and having the square timing dog on the left connect the positive lead to the second wire down and the negative to the third one down. With the ignition on set the voltage reading between 0.4 and 0.5 volts and tighten bolts, Disconnect connector for a few second and reconnect. If you do not have fine probes I found a couple of paper clips stategically placed works just as well.

Hope this is of some help redwine300 :duffer:

cheers bud, ive donme that, but i want t check it on a consult just to be on the safe side

 

cheers guys

Hi bud

 

Started the car today from cold and was a 90% improvement,i think i have a slight air leak somewhere on a vac pipe but overall well pleased mate

 

cheers Paul

nice one, will have another good lok at it at the weekend

Worth cleaning the connections behind plenum( idle control bits)

I went to change my idle controls over, it started snowing so i put connectors back on + its been a great idle ever since.
