rough idle

I rebuilt the engine some months ago, rebuilt the carb too. But since the rebuilt the engine runs unstable at idle. I have to keep rpm above 2000rpm so the engine keeps running. When I try to reduce the idle it enters into a cycle where it goes up to 2200-2000rpm and down to 1600-1400 rpm and...

Hi all, Please can anyone confirm the coil pack order on the Megane R26? I had my spark plugs changed last week but I'm not sure the mechanic took notice of the order of the coil pack. The car is now vibrating like mad and I can feel it through all the pedals, even when idle. The higher the...

Anybody have experience with the 1.5 dci lumps?? (Well i know a few of you will have :D) Just bought a clio dci 65 for a bargain price today. The issue i have is rough idle - but no warning lights on dash, pulls well with plenty of power - not bellowing out smoke and starts ok from cold. Not...

Hi All, my first post here. But definitely not last - all due to an old POS R5 from 1993 with 1.4 SPI engine, to which I'm emotionally attached and not going to get rid of ever. Biggest problem I have currently is the engine. Symptoms: - idles between 800rpm and 1400rpm - quite smooth in the...

Hi! Just got my hands on a R19 16v that hasn´t been running for 3 years. It starts fine but idles a bit rough (jumps beetween ~900-950 rpm) and during warmup i´t stalls without warning (it runs fine then just dies). After stalling I just have to start it up again and it runs fine, then it...
