Question What is wrong with my E30???

My car wants to stall and chokes, the second time starting the car. meaning when the engine is already hot, or warm from previous use.
but starting and driving from cold, sounds and runs ok.

its a 1991 318is, with M42 engine i belive.

inspection light is on the car, had it scan at BMW. its the oxygen sensor.

wires and spark plugs were done recently

any help will be greatly appriciated.
Thank u,

If BMW says it's the oxygen sensor, why don't you start by replacing that, or at least disabling it?

They also said it might not resolve the problem

No tricks. Ask Brent lol.. might not have ever been changed so it might be super welded in there from the heat after a long time being in there. It's going to be a knuckle buster for sure.

yep, I had to take it to a shop to get it rethreaded because they had to drill it out. It was welded on there good. I tackled it over a week trying different things. Penetrant, more penetrant, torch, channel locks, pliers.......all in all it just stripped it to shit to the point I couldn't even get my regular wrench on there anymore.

point of advice........don't take it to the stealership. Idk what good shop is in hamilton maybe someone could chime in.

+1 on that! I have yet to see a car stall because of o2...Might not run the way it should, but should not stall. Dealer is the last place i would take it to.
If you need, i should have some good cat/o2, and every othet part a 318i might need!

Yeah, I don't know the trick either, lol...I'm with Dave, it's not that hard to get at, it's just that heating, channel locks, wrench with breaker bar, PB blaster, and my mechanic couldn't do the job. I hear you pretty much have to heat it til it's red hot and then you can get it off...right now, I'm driving with it disabled, but my car's not stalling...

the car is fine when i first it from cold though,
its only the second time or after when i start again(hot engine), at the begining its choking, and sufficating, but then i go full throtle, it fixes.
only a little loss of power durring driving can be noticed too.

could the ECU or any electrical issue be related, i m just saying this, because the wiring look suspecious under steering wheel, wraped with duct tape. looks like its be changed?!

I have to get at mine soon also. I heard that you can use a Ford Mustang o2 sensor that BOSCH. Instead of the 100$ it's like 40$. Anyone ever try that out? I found a link for a guy who has a 325i that used a Ford o2 sensor and it worked.

It could be possible that your engine is flooding? Are you burning any oil or coolant? If so your head gasket or valves could be leaking.

Get someone to follow you on a drive and look for blue or white smoke.
Take a look at the spark plugs.
You can do some fairly simple tests to see if the O2, air flow meter, TPS, ICV are even working.

The dealership will only replace parts in hopes it "fixes the problem", most of them are useless without the diagnostic scanner tool. LOL

I have found the M42 to be temperamental, It seems to run at 80% most of the time. I have gone over the whole engine trying to make it run perfectly (fully rebuilt). It's been a real PITA at times.
