Fluctuating idle, bucking and stalling.
Posted: August 7th, 2005, 1:15 am
I have dropped in on a couple of threads and asked some questions but I think my problems warrant a new thread.
When car is started and engine is cold everything seems fine. Idle stable car normal to drive. Problems only occur once car has warmed up. Once warm the following problems show themselves
- Fluctuating idle
Unfortunately there doesn't seem to be a pattern to this. But it with move up and down from 1k to a point where it will almost stall and then shoot back up to 1k again. Other times it will shoot up to 2k and hold then suddenly fall below 1k and back up again.
- Bucking
Again when car is warm. Car will start to buck and loss power. When accelerator is pushed it will just splutter as though it wants to stall. If you take your foot off and let it coast the bucking and spluttering stops until you put your foot down again. This fault is very intermittant.
- Stalling
Will only happen once car is warm. When idle gets low enough and car stalls it will not start for at least a couple of minutes. Seems to happen more often when stopped on a hill or when clutch is pushed in.
I have searched previous threads and taken advice so far as to what could be the cause of the problems so this is what i have checked so far.
- have replaced plugs
- have replaced spark plug leads
- cleaned distributor
- checked intake lines and hoses, replaced air filter
Any other things I should be looking at?
