1) Yesterday on the way home from work I go through a small village, this has the speed humps that go all the way accross the road appart from the gutter. When going over these I put the near side wheels in the gutter and the off side over the hump, over one of the humps the car seemed to step out and track left, almost up the kirb. The back end also seems a bit 'wobbly' over bumps in the road. Any ideas what this could be guys ?

 

2) On Saturday I cleaned the throtthe boddies, reset the ECU and set the idle to 750 - 800 RPM when at correct running temp. Now when cold the idle is at over 2000 RPM and at the correct running temp idle is at around 1100, occasionally it will drop to 750 -800. It was running at around 1100 RPM before I started the work. I also cleaned the TPS connectors. Any ideas on this one, is there anything else I need to look at ?

(also cleaned the connector on the thing near the battery where you adjust the idle speed but can't remember what it's called)

 

 

 

Cheers for your help.

The skipping could be either worn shocks at the back or worn bushes or dues to the wheel alighnment being out. I had this problem and after having the alignment done, she was a different car. There is a top place in notts that does this called the 4 wheel allignment centre, in old Basford I think. Only about £40-£45.

 

The idle problem could be due to your TPS being incorrectly set. It should be set at 0.44v. If you cant get to a Conzult, the easiest way to set it, is to opn out a paper clip and slide it in to the middle pin of the TPS connector while it is still connected. Then earth your multimeter and put the positive end on the paper clip. If it's out, loosen the screws and adjust and then correct the tickover.

Cheers for that Cos, I will get the wheel alignment checked.

As for the .44V, is this on the connector on the TPS or the larger connector on the flying lead coming from it ?. I take it to adjust it you actually move the TPS unit itsellf.

So what was the thing I adjusted the tickover with, its a unit at the back near the battery, was this the wrong way to do it ?

1 - also could be HICAS link arms

 

2 - try cleaning the engine temp sensor & connectors, chech for corrosion at the back of the terminals. you can get a new sensor & loom from Courtesy

Alright chaps, right then, set the TPS to exactly .44V (with my calibrated meter from work) and checked and cleaned the yellow temp sensor connectors and adjusted the 'thing' near the battery and got the idle to around 750rpm. After a few seconds it started to creep up, kept adjusting it but couldn't get it to settle any lower than around 1000 - 1200ish. This morning the idle would hover around about 900 - 2000 rpm, any ideas guys ?

help, anyone, please ?

I had trouble with my revs bouncing all over the place, this was due to the temp sensor on the coolant hard pipe (between timing belt cover and fan) being covered in green stuff......

 

Took it off, cleaned both ends and it cured it right away, constant idle and no hesitation when moving off.

 

Been 11 months since and still no problems.

 

I know once you clean the Throttle Bodies and then reset the ECU it takes about 100 miles for the ECU to 'relearn'.

 

Matty.
