Might be worth opening up the throttle body and compare with this vid below. Odds on, at 175k your throttle potentiometer is fairly worn and thus causing the problems. I'd have a look at the wiring loom on the t/b also.

Well, water is a bastard. And if the problem was highlighted by water ingress(very possible) it may suggest it's a wiring loom or connection issue but either way you can be sure your T/b has seen better days. It could be 550 bucks well spent. Finger crossed.

Ha, it was train sets for me. Use to open up the the transformer (dial type), give it a good old 'cleaning' and of course it never worked afterwards!Originally Posted by Vetruck

Well, Dean if it's any consolation you can be sure it's not just your car that has or will have this wiring problem. W202 owners should take note, especially on the earlier cars.
I'd say too you can be fairly sure this is the problem, also there's a very good chance the car will drive far better with the new T/B. Looking forward to an update.

Funny you mention vacuum pipes. Changed the FRP on my car last week and found two slits in the rubber pipe connector. Age is taking it toll sadly.

Now I can get back to the fun stuff of modifying it. That resumes tomorrow morning (Evil smile)
Delighted to hear.

Dean, I understand it always advisable to disconnect the battery for something like 20 mins after replacing a faulty part such as your T/b, Camshaft position sensor etc. Thus the engine ECU learns very quickly a new part has been fitted and I've also been informed it takes the guts of up 200 miles before the ECU has done it's relearning. So, if my info is correct it would make total sense what you are experiencing with your car now. I can say from first hand experience on my W202 when I replaced the Cam sensor and MAF the car drove even better after a long journey and that was not my imagination getting carried away.

Thank you John for helping confirm my assumptions. I am going to give it a little more time before I even try to clear the code with my scanner.
I like doing play by play descriptive post so it helps any future people troubleshooting a problem. I always try and document my exact steps.
I should also state that the battery was disconnected during the time I pulled the car apart to change the TB. I never work on electrical stuff witht he battery connected. I made sure the system was clean and clear of codes before I diconnected it and started the work two days ago. I even had to dig out my manual to reprogram my radio code.
