Hi folks.
I just want a bit of advice on how to get my damn car running smoothly again.
First off I'll let you know that its a 4 cyclinder 8v engine (I know....its not worthy of the forums, but my future intentions are ).
Recently the car has been extremely lumpy on tick over, some days it is much worse than others depending upon how long it has been left on the roadside waiting for me to use it, generally the longer it is left, the better it is until I have warmed it up and start using it more frequently again. The lumpyness is almost like a very fast but very faint shake, almost like a really fast miss on one cylinder.
Firstly I thought it could have been a slight blow on the gasket, but after having a compression test on the engine, the car seemed to come up fine. We did notice that one of the engine mounts had broken and another had come loose, so I had the 2 front engine mounts replaced hoping the judder I sometimes get when I pull away would be fixed....well it has improved but is still not great.
I have been told that a lambda probe can truely transform a car, well, being a 1990 8v I dont beleive this car actually has one, so unfortunatly that seems out the question. Next on my list was the mass flow air meter but this car actually uses a jetronic style fuel injection system developed by bosch, having checked it we found the engine was running lean, but apparently that is normal for this type of injection system and car.
The audi specialist we take it to is a great beleiver of actually repairing as apposed to spending a great deal of my money buying new parts, he doesnt like to give people huge bills and will do all he can to avoid major work unless of course he has to, and seems sheepish passing a highish bill across. He is a great guy and obviously knows what he is doing but his method of thinking is that so long as I have this rough idle and its not doing any damage, then theres no reason to worry about it, but tbh, I hate the idle, it irritates me everyday I drive it and Im not sure what is causing it...I think its the fuel injection system.
Oh and one other thing, if the car is cold it starts up very well because the mixture is lean, and if the car is warm it is also fine, but somedays I start the car up and it wants to stall and just manages to remain running or it does stall. If I try and start up straight after it has no problems starting but then starts idling badly.
I have been told these are characteristics of this engine and with age and high mileage this happens. Apparently I could be spending far more money than I would want to on old technology and instead should just be content with how its running now.
I know its a long post, and may not make a great deal of sense, But I am truely mystified.
Any help guys?
