Hi all
I am new here, and also new to BMW... as an owner anyways. I'm an Audi guy, yeah yeah I know.... :)
I just picked up a 1989 325ix a month or two ago and went through just about everything which I'll get into here in a minute. I'm looking for ideas on chasing down an issue that didn't start until after I replaced the head gasket, so had a ton of stuff apart obviously.
Car: 1989 325ix stock as far as I know 253xxx miles
The car had an extremely high idle when I got it 2000 Rpms. Several torn hoses etc all replaced and a torn intake boot. The head gasket needed to be done so I did a TON of stuff while in there.
My issue now is that I get an intermittent engine cut for lack of a better way to word that.... seems to mostly be in between shifts especially when letting off the throttle after being WOT. CEL will flash, car bucks a few times then straightens out and is fine. Occasionally I'll get a CeL when the car is sitting at idle which can be sporadic but usually around 800-1000rpms. If you tap the gas the CEL immediately goes off. Doesn't appear to come on during normal driving or when I'm hammering on the car only in between shifts or as otherwise mentioned if I release the throttle quickly after being 50-100% down. Stomp test reveals one code 1222 which can be 6,000 things most of which I've replaced. No vaccum leaks that I have been able to find.
Now this issue started after doing the work and replacing pretty much anything and everything I could think of, I'll try to list it all below. I have been trying to track this down for weeks so any help is much appreciated.
Replaced:
Head gasket and bolts
Timing belt and tensioner (timing is fine)
Water pump
All radiator hoses
ICV
Intake boot
All vaccum hoses (that I know of)
Blue and brown temp sensors
Fuel filter
Intake filter
Plugs (twice to make sure)
Rotor and cap
Fuel pressure regulator
Throttle position sensor
Valve cover gasket
Oil cap
Fuel cap
Charcoal canister
Purge valve
Exhaust gaskets
02 sensor
All cooling system stuff (radiator,thermo, etc)
Not replaced:
Ignition coil (ordered)
Fuel pump??
Ecu? Have had a bit of water or moisture in glove box will pull ecu to see if it's got any on that.
I am also wondering if it's the TPS... I lined it up as best I could w the old one but wasn't sure if there is a specific way to line that up and wondering if the throttle is not closing or opening properly under certain conditions? I've read it should make 2 clicks... one right when you activate throttle which I have and a second at about 70% or so throttle, I only have one click not two.
