Hello
I recently purchased a 15 year-old black E30 316i. It's my first car and I'm a little unfamiliar with the lingo and the technics. I've had it for about a month and I'm getting the impression that this car has been neglected somewhat. As I want to hold on to it for as long as I can, I'm in need of some advice. These sorts of engine troubles have probably been discussed before, but I'd like to tell the story in full. So here goes:
When starting cold the engine runs fine for about 10 to 30 minutes. After that, when in idle, it gently bobs from 500 to 800 RPM and shudders somewhat. At this point, when I hold the throttle at +/- 2000 RPM I can hear some random poofs. When driving, again after some 20 minutes from starting, the ride gets a little bumpy, but it still works. This only happens when I accelarate.
Now, in reading some posts on similar problems I ran into all kinds of solutions for all kinds of problems, but I'm not sure if mine's the same.
-should I do something about the ICV, and if so: what?
-Could the fact that the cap on the gastank is missing have anything to do with this (I've ordered a new one)
-I'm inclined to replace the spark plugs. Should I? And what should they be like?
-I'm going to do an oil change, which is best, and should I use one of those flashy additives that "greatly reduce friction"?
-I'm going to use a product for cleaning the injectors. will that help in any way?
Does cleaning or changing the air filter help?
-Do you have any other suggestions?
I'm willing to put some tender loving care into this baby, but I'm strapped for cash at this time. I've ordered a service manual to get to know the car properly. I learn fast, faster with some help .
Greets & thanks,
Mark
