Hi all, I have an Renault clio 1.4 1999 that has has recently started playing up and now is unusable. The car initially had a idling problem which caused the car to have a very rough idle to (attempt to fix this) we replaced the TPS sensor, Map sensor and the ICV, on the intake. But sadly that never fixed the issue to we replaced the coolant temp sensor and that two did not fix the issue. We then had to use the car so we just turned up the revs to 1000rpm to get by so that we could use the car for a bit but at the end of the week the car didn't want to start. The car would start and when it did it would start at 4000rpm then after about 5-10 seconds would fall to 2000 and keep bouncing up to 4000 and down to 2000. Prior to I'd doing this the car (in the week that it was working with turned up revs) began being lethargic at acceleration and due to this I have decided that the fault could be to do with the crank position sensor so I have ordered this part today (25/10/16) and hopefully this can solve the issue. If anyone can give any insight or ideas that would be great as the car is amazing otherwise when it runs and it's much cheaper then my alternative car to fuel. If you have any ideas that would be great, thanks for reading it all anyways. Regards Kamikazzee
