Problems with my 1989325i

Hi I hope someone can give me a clue. Recently the timing belt went out on my BMW that has only 48000 miles on it. I took it in, they replaced the starter, the timing belt and the heads on the engine then gave it back to me. It didn't run right, sounded high on the idle, so I took it back in and they told me the idle control valve needed to be replaced. They did it and now its running worse. It keeps dying and jerking. Dying in idle but even when going. They mentioned the sensor might have to be replaced but why would it run worse after replacing the idle control valve? and does the sensor regulate this valve or effect it? Any hints would be welcomed, this is getting to be overwhelming because I've already had a lot of work done. Thanks.

i dont really know the answer to your question, but was your timing belt the original one from 1989???

Hi, no supposedly they replaced the timing belt that's why they also replaced the heads.

i would say they may have knocked the cps off just a tad

what is the "cps"? They told me that if it was still not right after re-doing the valve then the sensor needed to be replaced.

Buddy, I think you went to the wrong workshop
If they give you a car that does not run right after replacing all of this, they should be ashamed !

too true, but unfortunately too late now!

More likely than knocked it off a tad they cracked the wire when they installed the head .Probabaly didn't route they wire the right way.They get really brittle from the heat and crack easily if your not careful .The CPS will give you the problems you describe and soon the car will not wan't to work at all it will just crank and crank and won't start .Then if you wiggle the wire sometimes you can make it work again for a bit .Bottom line you need a new CPS but it's their fault and they should be paying for they're mistake.

crank position sensor. since everyone else described symptoms and not the meaning.

I take it valves got bent when the belt went?

Even though whitehot77 is under the impression he has more than one head it sounds like they replaced it.

I haven't seen a 48k 1989 325I since about 2000 and I thought that was low mileage.

It is most easy to adjust the ODO to read what you like it to

Yeah after replacing the gears twice I've just left my 325i at 180k .I think somebody duped him if he thinks his 89' has 40k on it just nobody fixed the ODO since it had 40k and now after fixing it it looks like it's been working all along.Oh well
