Need Raleigh area FI troubleshooter

I am in need of someone who has the necessary test equipment, pressure testers, etc., to troubleshoot what I am thinking is a fuel injection problem in my Mondial 8. Someone familar with F cars would be good but that system was also used in MB, Volvo & VW's.

More info on my problem can be found at...........

Any suggestions?

Thanks,

Monday it is going into a shop.

On the recommendation of another F-chatter I found a shop and a mechanic that is very familiar with the CIS on my car. Note I did not say the car itself, just the CIS. The shop is actually (wait, button, button, zip, OK, flame suit on) an independent Mercedes shop. They have a fellow there who has been doing Mercedes work for 30+ years. That was back when these CIS systems were fairly common. Plus he has the necessary CIS testing equipment.

If I don't come upon any great revalations between now and Monday I will give him a crack at it.

I will let ya'll know what happens.

AT LAST !!!!!!!!!

Got the car back this afternoon and it is running better than it ever has since I bought it in August.

As it turns out the biggest problem single problem was several reasonably small vacuum leaks. Individually each did not amount to much, but taken together, big problem. There were several cracked hoses, naturally the cracks were on the side one cannot see with the hose on the car, and a vacuum line leaving the throttle body and going no where, the end was hidden and I missed it completely.

The leaks were causing an overly lean condition that did not really show itself until the WUR got to the full lean (engine warm) position. Hence it would run fine for 30 minutes or so then start missing, hesitating, and in general just not have enough power to get out of its own way, unless floored. When floored the problem vanished because just enough extra fuel was dumped in to get the mixture to a level where it could actually burn.

I like the way the mechanic, Neal, found the leaks. He “smoked” the intake. Took off the plenum hose, blew smoke into it and then looked around to see if it came out anywhere, did it ever. Nice idea, wish I had thought of it.

The mixture was also adjusted to richen things up a bit. I did find out the fuel distributor is showing its age but that I have at least a little time before it is totally used up.

I gotta say I was a little apprehensive about taking the car to a shop (The Car Place) not known for doing Ferrari work but Neal and Ronnie know what they are doing especially when it comes to CIS injection., they are true mechanics. Almost anyone can learn how to replace a part on cars they have become familiar with but a true mechanic, when faced with something new, will take the time to understand HOW something is supposed to work. That makes figuring out why it doesn’t work MUCH easier and frequently much cheaper, they are not just throwing parts at a problem hoping to stumble across a cure.

Three cheers from me to The Car Place and Neal and Ronnie.

Also a special thank you to fletch62. It was his recommendation that lead me to The Car Place to begin with.

PS: Fletch, sometime in the not extreme future I need to talk with you about the possibility of you rebuilding the fuel distributor.
