I'm glad you figured it out, I'll bet your thrilled! Thanks for taking the time to post the solution too, I've heard of this happening with many types of aftermarket sensors on more than one occasion.

After owning this car for 3 years and never getting the full potential till now, I am extremely thrilled! And despite the fact that I spent more than necessary, she runs sooooooo smooth with all those new parts! Now to focus on some chassis reinforcement to help with that convertible front end shake and then on to cosmetics (possible Laguna Seca Blue)!

I WANT EVERYONE TO KNOW THAT THE BACKFIRING THAT I REPLACED MY ENTIRE ENGINE MANAGEMENT SYSTEM TRYING TO FIX WAS AN AFTERMARKET CRANK SENSOR. The $200 crank sensor from BMW FIXED ALL PROBLEMS, NO MORE BACKFIRES OR CAM SENSOR CODES.

So I got the exhaust redone and new o2 sensor put in and idles smooth at startup but still backfires while cold if you rev it or put it under load. Going to replace the Crank sensor with OEM BMW. Apparently there are none left in the US and they had to order from Germany.  The only other thing I think it could be if this doesn't completely get her back to spec is fuel lines clogged or burnt valves.

Have you tried a local muffler shop? A lot of times you can get custom piping put in for way cheaper than buying a pre-fabricated piece. I only paid $300 for my local shop to install custom from the header back. He installed a Magnaflow muffler, resonator and tip as well, but it is a little loud and I might be going back for a different one. (no cat, it's federally emissions exempt at 25 years)

Anyone have a working Instrument cluster for an e30 m42 that is in good condition? I am in South Florida.

Car runs great with new AFM (I wanted to get it installed right away which is why I went ahead with the Cardone rebuild instead of getting one from someone on here). Will be replacing O2 sensor this weekend pre-emptively (I had already bought it anyway).

Anyone have experience with Cardone rebuild AFM? $185 is looking pretty nice compared to $660

Also funny story, the AFM, when unplugged, would still not allow the car to run well. When I disconnected the AFM from the car completely, the car actually runs okay.

Pulled the AFM out and it sounds like a Mexican Maraca when you move it around. Guessing I'm going to have to bite the bullet on this one.

Hooked up an auto logic scanner and temp sensor is reading fine. O2 sensor goes back and forth between normal and adding massive amounts of fuel. (0.4 to 0.. Does anyone have a list of what normal operating values for all of the inputs should be? Also, even with the non-cat wire disconnected it still reads a co value, but I also noticed that the co wire connects to the TPS input. Still getting codes for lamda control and cam sensor.

So I replaced the injectors with brand new and the car actually RUNS  but it still hesitates, misfires, stalls, and backfires while the engine is cold. It starts really badly and the warmer the car gets, the the better it runs. (I have replaced both temp sensors) For instance when I first start it the idle will be rough and car will backfire and it may stall, after a minute or two the idle will have smoothed out and the it will backfire under any load or revving close to 2000rpm. Then after a few more minutes it will only hesitate and backfire about 3000 rpm. As soon as it warms up to operating temp the car runs PERFECT. It is almost as though the car is not enrichening the mixture as it normally does while the car is cold. Any ideas?

I think a 318i is the same afm, get on of those secondhand on ebay?

Can't always be 100 percent sure it's working correctly. I started to look around for ways to test the one I have presently as it looks fairly new.

Have you tested your ignition coils?  Also, what condition are the plugs in?

Coils, wires, and plugs have been replaced.

Btw isnt 1222 code a lamda sensor issue? Also just check the resistance of each item you think might be failing. Another option find a local "guy" that has software that you can hook up to the obc. That way you can see live if data and if all you sensors etc are working in order. Also any issues with you new or old ecu will surface pretty quick.

From everything I've gathered, 1222 mean it is either too lean or too rich. It could be a lot of things. The car seemed to run the worst after I put the rebuilt injectors in and cleaned out the carbon so I decided to just buy brand new Bosch replacement injectors (the new ones come with the four pintle head anyway). The car smells rich but can't be sure. I have a crap ton of BMW software but it seems to cut off right before 1992. It doesn't seem to read the values.

I swapped out the ecu with a used one, started up, and it runs even worse...buuuuuuuuutttt..... it now reads codes (so I assume the other ECU did have an issue)! I am getting a code for 1222 which still refers to a driveability, mixture issue. Could it be a bad AFM? shelling out 700 bucks for a question mark is intimidating.

What is the ECU number on the sticker? i.e. 0 261 200 175

Installed BMW cam sensor today and still runs like crap. No Check engine light but computer throws cam code 1244 even after disconnecting battery for 5 minutes. I even unplugged the air flow meter which got the check engine light to come on but it still only throws one code.... 1244, doesn't even throw a code for air flow sensor!! I read that someone else here had a similar experience and it ended up being the ECU. I've had my ECU tested but do you think they missed something?
