My 82 245 has started to idle very rough and cut off while idling. He runs and idles very strong in cooler weather, but seems to do more poorly in warm weather. I was told by two different friends that maybe my air mass meter was on the outs. Any thoughts? thanks in advance

82s with Lh fuel injection are fairly rare, are you sure you have one? An air mass meter that is. If so you can pick up used ones on ebay for 30 to 40 dollars.
If yours is a true 82 it may have an 001 but an 002 will work just fine. These are the last three numbers on the massmeter. good luck

Not at all true from what I've been told, by reliable sources. 001 AMM is the only one that can be used in LH-1 systems. To use an 002 you would need the corresponding LH computer for 002 AMM. From what I've been told, the 001 is backwards from all other Bocsh AMMs. A computer/AMM swap may be the way to go, as 002s are more available than the 001s.
Just an FYI...
Thanks...

Chuck, I was just looking in the 82 factory Lh book and noticed that the 82 has a seperate Idle speed control box so the computers can't be interchanged. I don't know if the 002 will work on the 82 but the 001 definately works on the 83.

Thankyou for calling my attention to air mass meters as when I went out and looked I have bought a little ahead of the demand I have. I currently have at least (20) 002s (5) 007s and (2) 016s!!!! My god thats a little over kill on the 002s!! In addition I have one factory marked 001 and I put it on my wifes 83 and it works perfectly. At present she is running a 503 computor but I also install 510s in there all the time to run for a week to check them. My guess is that if an 001 works in a 83 that an 002 will work in a 82. My guess is that after working with Bosch for 30 years the one thing I never remember them doing is reversing leads on anything electrical.

Thanks for the info. Guess my reliable source wasn't as reliable as I thought. Are these AMMs just spare parts, or do you sell them??
Thanks again.

I pick them up at the local wrecking yard and on ebay and then sell them to the local shops. They are basically for people who can not afford rebuilt ones.

Megan,
Is it only an idle trouble? Does it run and drive fine other wise? If so I don't think its your AMM, I've had my original AMM for 234K plus miles and its still fine. Only some 82s had the AMM. Do you have the LH setup, with the wires going to the injectors? Mine has had this trouble off and on for years, cleaning the throttle body helps for awhile, also the idle motor cleaning helps too. Check for Vacuum leaks around the injectors, and the throttle body and the intake, check all lines for splitting. Also check your intake hose after the AMM. All sources for rough idle. Good Luck...

thanks Chuck,
Well it started as only a rough idle, but yesterday (for the first time) while rolling up to a stop light- in first gear -my car shut off. I do have LH also. How exactly would i go about cleaning the idle motor? I'll also look at the hoses and wires you had mentioned.

thanks, Megan

For mine I used throttle body cleaner in an aerosol can. Disconnect it, 2 large vac hoses and a wiring plug. Spray the inside of it until its clean, and makes sure the little flapper inside moves freely. Then connect it back up. If it was me, I'd do the the throttle body at the same time. Stuff will be out of the way, also a good time to do the flame trap and oil separator box, check all those vac lines under there. One more note. My 82 does not have a throttle position switch, so no need to worry about getting that right, in the past I have just adjusted the idle speed screw to get me more time before cleaning the throttle body, it works. Also I'm sure by now you know about the fuses. I've had stalling problems from fuse 13 being corroded, also check electrical connections, have had no start from them. Lots of places for trouble on an old car, unfortnately, I think I've had just about everyone!!!
Good Luck...
