starting problem

These parameters can be recorded with any OBD interface connected to a laptop. I use ELM327 (£20 on ebay) and ScanMaster software, which comes with it. Just select all parameters available for this engine, start recording, then start the engine, idle for a while, rev it a few times, then drive, then stop recording. Once it is done, plot the data either with the same tool or Excel (free OpenOffice is OK), print to PDF (e.g. free bullzip PDF printer driver) and post it here. If you don't want to post it, then show it to someone with knowledge in engineering and use the manual (MR366MEGANE1.pdf MR364MEGANE1.pdf files in the sticky thread above) for reference.

The diagrams, for example, may show inconsistent temperature readings, which will cause the ECU to stay in the warming up mode (rich mixture - smell), or may show increased calculated load at idle, which is a characteristic of dirty throttle body. O2 sensors may be playing up, the MAF sensor may be giving inconsistent readings due to air leaks or blockages, etc.

One more idea. Disconnect the dephaser valve temporarily. Your engine is supposed to idle normally without it and the car will drive fine in low revs. If an improvement is detected, then you'll know where to look for a fault. BTW, are you sure that the timing was done properly when changing the dephaser? Most garages employ people who don't read the manuals...

thanks for ur info guys what and how do i find out about the parameter's? i will pass all this info on 2 the garage and let u know the outcome thanks again .

thanks i assume the timing was done propley it was checked a few time as this is what the garage thought the problem was at 1st and something 2 do with pistons and the defaser pulley (full kit )e.t.c. so it was looked at and checked by 2 macanics , it wasnt a little back street garage neiter it is a huge garage named e.r.b it does everything from buses 2 cars well known
