I'll take a look. I should have noticed though when it was off and sitting on the workbench.
And I drove around for two days and about 40 miles after the fuel pump but I haven't taken it to work which is the real test. For whatever reason it always acts up when I go to work must not like my job.
Well mine is warn from water pump pulley rubbing on it in the accident doesnt even look to bad but i have every problem that guy did, to the T.

Well 150 miles after the pump replacement and it's still running great.
What do you think is it possible for the fuel pump to suck air in if the clamps aren't tight?
I would assume that it would leak and not suck air in but I did notice that when I replaced the pump one of the clamps broke so I needed to use a new one.
If the first pump was somehow sucking air in the line I could see it running like it did.
But with all of that pressure I would assume that if a clamp was lose it would leak not suck in air.

So far so good it's running great I've been driving it around all weekend.

I've had the cluster out to replace the odometer gears it's all clean.
I didn't think that the sensor to the dme ran to the cluster only to the dme.
I thought the blue sensor ran to the dme and the brown one went to the cluster?

Back to the drawing board. Took the car to work on Friday and it did it again.
If anyone needs a perfectly good fuel pump my new VDO pump will be on ebay shortly.
I just don't get it I think it's my job that's screwing up the car.
I drove it around all day today again and nothing it ran perfectly.

You guys, do you have a crank sensor? If so, has that been replaced too? Could be that when the car reaches operating temperature, the crank sensor's resistance shoot high and what results is a high rpm misfire. When it does it again, keep at it, don't let off and note all the symptoms - I bet you the car might even die or lose power significantly!

It's just to intermittent to be a mechanical failure for mine It has to be electrical.
I can drive the car for 200 miles and there's nothing then the next day 5 minutes in and it acts up.
I may resort to threating the car keep a can of gas and pack of matches in the trunk because I think it's just doing it for fun.
This is unlike any problem I have ever had with any car.

just a quick thought, do these motors have a knock sensor? i cannot for the life of me remember, but my subby did the same, changed everything fuel related, still happened, took it in to the dealer cause they wanted to see if their mechanic changed the knock sensor (and he didnt) replaced it, and since then, no problems besides the knock and tranny issue.

What Exactly does it do when it is having its episode like as you hit the gas and does it make any noises?

It's hard to describe. I guess it would be kind of like hitting a rev limiter at 2-3k you can't continue to move forward without flooring it.
And it's not that it even maintains the speed at a low RPM the more gas you give it the slower the car gets until the final point when the pedal hits the floor then you get full power again.
Well until you back off of the pedal then it's the same thing the car will hesitate and not move be able to maintain it's current speed until the pedal is pressed to the floor again.

No smoke no gas smell no poping you just can't maintain a set speed

The fact that your water temp gauge acts up suggests to me that there is a bad connection between the DME and the instrument panel, or that the i/p is poorly grounded. I had a problem with an intermittent bogging/misfire that coincided with the water temp gauge acting weirdly.
If the car was running fine, the gauge would be fine.
If there is a bad connection between the i/p and the DME, the DME is going to be confused and late.

I've been looking over the wireing this has to be the worst problem with a car.
I just can't find the short.
I have some crappy alarm system spliced in under the dash that doesn't apear to be doing anything I may try removing that to see if that's causing some problems.

Sure PM me,

I still have not found a solution though.
I haven't had a chance to look at the car over the winter and the few times that I did drive it the problem did no occur

OliverM3,
Have you made any further progress with this? Were you able to find a solution?
My car is having very similar issues.

I have not it's has proven to be an elusive problem.
I recently sold the car to a friend he's going to give it a shot.
I'm still leaning toward cutting off that damn C191 connector because when it's acting up the temp gauge bounces like it's an electrical short.

I'll definitely post back if he manages to resolve the problem.

I've seen a few posts with similar problems, but nothing with a definite resolution. Seems like most sell the car before they resolve it. My car (86 325e) has an intermittent hesitation while accelerating between 2000 and 2800 rpm, and over 4000 rpm. The weird thing is, like yours, sometimes the car drive absolutely perfect.

When the problem happens on my car, it creates an extremely fuel rich situation. I get a lot of black smoke from the exhaust, and my fuel economy on the OBC goes down to like 7mpg; when it works normally, it is around 20mpg. I wish I could figure this out.

I finally sorted out my hesitation issue. It had gotten to the point where the car would only idle for a few seconds before stalling, then it wouldn't start at all. I knew the car was running extremely rich and thought I'd addressed everything to cause that rich condition. So I pulled the spark plugs to have a look at them and they were terribly fouled. I replaced them with clean ones and the car fired right up. I drove it around for a while and there was no hesitation, hiccups or stutters at all.

I had recently replaced the plugs, but it that was before replacing other things to address the rich condition. I guess all the extra fuel had fouled the plugs, which caused them to not spark, thus causing more richness; not sure just my theory. What I do know, is that it works well for now. This was just yesterday and I only drove a few times, but every time I did, the car ran flawlessly.

If you are having a similar hesitation and fuel rich issue and you've repaired or replaced the parts you think caused it, make sure to check your spark plugs afterwards.

You will be surprised how a fouled, worn or incorrect plug can affect your cars performance & consumption

For laughs, this is the old fashioned way of cleaning fouled plugs
