What are some typical causes of my car running lean. I'm not to fimiliar with this. Could it be in relation to the boggy feeling at low RPM's?

clogged following.

Fuel filter
injectors
fuel lines
lambda sensor (o2)


I would check them in that order.

thanks

already changed the fuel filter and o2 sensor, i checked the lines for pressure and seem good so i'm assuming nothing is clogged, and the injectors i'm assuming are fine, the were tested when i did the motor last year, and have ran injector cleaner through them a couple times since then but make one of them went

How can you tell if the car is running lean or not?

we know what the problem is, we told you what the problem was, were asking for solutions or probable causes

well it seemed to me that u guys had it backwards...but ok np. a solution is to check ur air filter and see if u need a new one. it also depends on the climate. do u have a carburator on ur car or a fuel injection?

i've done all the check up things, filter, injector cleaner, fuel filter, plugs and so on.
i'm looking for an internal problem.

Of course it's fuel injected i'm pretty sure all E30's are as well as all other BMW's

actually I thought the 325 (Without I designation) was a carbourated model. The i was (to my understanding.) to stand for injected, like fuel injected. So I mean... I guess that was just my immedeate deduction. Anyhow, I'm not often right. :P
