I have a year 2000 selespeed which was running perfect until service yesterday and routinely cleaned throttle body with cleaner and a rag by removing intake pipe, today it flutuates frome 1500 - 2100 revs making every 1st gear roundabout a pain and jumping forward with the selespeed auto clutch - its undrivable at slow speeds! i tried the 90 second on key 90 seconds off and start but it creeps up to high rpm again - ive also reset ecu but still have fault! any ideas? :cry:

try removing the throttle body and clean inside and out (only a few screws to remove) as there may be some muck inside that is causing the problem (this worked on an old citroen i had, same fault)

i had a close look and found that the pipe between maf and throttle body was split. so i repaired that and done a throttle reset but its still rubbish, if i come to a roundabout it goes to 2500 rpm but if i give it a good rev it idles normal! it make driving the selespeed like having a piggyback from a kangaroo!!!!!

a full stripdown and clean of the throttlebody should solve it, you have probably washed some of the muck inside with the cleaner or possibly got some muck in the butterfly hinge causing it to be jerky in operation

Whats happens when you reverse the car? does it jerk or is it fine? mine is very similar to this, but it doesnt do it when in 2nd gear start, reverse or a standing start after a gradual roll forward, thanks

My old 145 did this when i cleaned the throttle body. I tried the ecu reset by disconnecting the battery but it made no difference, so ended up taking the car to my local specialist who had to do a reset with the diagnostic software. Something to do with the throttle butterfly being moved that it does not like I think.....

What you can do is open up the TPS and clean the cogs off, they get dirty and you've possibly pushed some grit through from the throttle body throat with the carb spray, this is the component (at fault)that's telling the ECU to throw in more fuel, not a selespeed problem. The resets wont work because the TPS is still dirty.

If that still fails then squirt the Throttle body flap bar at each end with some silicone spray like GT85 to lubricate the bushes.

Had the same problem on my old 145 and on my current jeep wranger (sorry:eek: ). In both cases some sensor had to be replaced. The jeep needed a crank sensor according to the dealer but that didnt make sense to me. Paid for it and its fixed is all I know. Maybe a diag test will shed some light

When you cleaned out the throttle body did you move the butterfly valve with your fingers? Also when you say you repaired the intake between the MAF and throttle body did you replace it or 'fix' it?

right then, the latest!

i removed throttle body and cleaned perfectly and checked gears for damage, put all back together and took for a drive!

drove so much better but idle at 1050 - 1100 book says 900 so i carried out a throttle reset!

now when i started it it reved to 4000 for ages and red injector light came on! and stays on!

now im just doing a 45 min ecu reset to see what that achieves!!!

any ideas?
