    I gotta say thank you for this particular post. I recently had an autocross test and tune session, lots of seat time. First half of the day was one direction, second half reverse course. During afternoon course my car stuttered and the check engine light came on. Got home and had a tough time running the stomp test. After about 15 tries finally got P1216 for TPS sensor. Replaced the throttle body with a spare I had, but same issue. P1216 again. Searched R3V and found this post, then inspected my TPS connector. One wire broken, just like yours.

    I tried de-pinning the plug so I could repair it, but couldnt get the pins to release from the connector. Ended up buying a generic connector and spliced it in.

    Today was test/tune day for autocross, so it was loosely organized to get as much seat time as possible. The first half of the day had two split short courses and you could chose to run whichever one as many times possible in the allotted 45 minutes. I didn't shut the ignition off until our full session was over. Well over 20 runs betwix the two were had and the 4.44 LSD has transformed the car. I'm now fighting some oversteer, but until I put the new tires on, camber plates, and a good alignment I'm not touching anything. I was hitting the rev limiter in one straight, but right at the tail end of it. Time wise I did well compared to my competition with far more tire and power.

    The second half was the split courses connected and some of it flipped backwards. I was 2 seconds off my nearest competitor, but I scrubbed too much speed in a couple areas I need to work on. We only ran 6 total but all in all I felt more confident in the car. Unfortunately as I was finished up the 5th my check engine light came on. After throttle was open past idle it ran fine, but sputtered at idle and if the throttle was stabbed it would surge. 6th run it stayed on and the symptoms remained. When moving the TPS harness at the plug the idle would change as if it was a bad connection.

    I got the car home easily as any throttle above idle appeared to be normal, and only at lights would I have to apply some throttle to ease idle surge. Google told me to do the stomp test and no matter how I did the test it wouldn't trip the light flash. It seemed obvious at this point the TPS was suspect, so I removed the one on the car. Looks brand new, so I swapped it with a used one on the field motor just to see if it would make a difference. Same. No light flash after 5 pedal stomps. At this point I decided to check the harness. Stripping back the rubber boot shows a broken wire on the #2 pin. BINGO! I stripped the wire casing back a little and jammed it tight against the pin. Stomp test code shows up now and it's a 1216.



    I've got a spare motor harness, so I'll just wire in a different plug after checking to make sure it's not tearing at the crimp like this one. Anyone know how to just replace the pin on the plug?

    So we had another autocross back in November, yet somehow I forgot to update the thread with info and pics. I finished 16th overall out of 48 which is pretty damn good for me considering the field of amazing drivers and cars I'm up against. Still need to get some front swaybar action or just stiffer springs, but at this point the car is about to be retired from autocross duty. At least it won't be going as often as it has.



    What I'm trying to say is the e21 I picked up last year has been getting the old m42/trans from this scuzzlebutt 318is installed in it. I've fully gutted it, and will be running in XP all 2019 season if things go well. 2020 may be allowing like motor swaps, so it could potentially be a DP car with a weight penalty. It's also getting built for the GRM 2019 Challenge, so it's all on a super tight budget. I'll start a thread here in a little while to catch everyone up. Oh, I also bought a 63 Baja for the next Gambler 500 near me in the Ozarks and possibly one in Kansas.

    It needs installed bad. That and some harness setup because I'm all over the place trying to stay put in the seat. Unfortunately I just moved into a new house last Friday, so my garage isn't quite as functional as I'm used to.

    So Hoosier has a closeout sale on 225 50 14 a7s. $100 each with a flat rate of $15 shipping no matter how many tires you order. This works out perfect, as I have the stock weaves laying around that will eventually be used for the GRM Challenge e21 I'm working on. I decided to give these a try last at last Sunday's autocross on the e30 to see what the fuss is all about. YES. I will take a truck load, thank you! I knocked roughly 4 seconds off my normal times, and with some seat time I think that could end up being another second quicker. Maybe. Either way, I love the new found grip. So I ordered another set, putting my grand total for two sets at $830. Way less than shelf price for just one set. I've got another double header this weekend, so hopefully I can climb my way to the top of the pack.

    So I forgot to put up some pics from last Sunday's autocross. It made getting the AC fixed a high priority. We saw 100+ temps Thursday and Friday, so over the weekend I did my best to get everything installed. Dryer, parallel flow condenser, expansion valve, r134a pressure switch, evaporator, and of course some Pag oil. I was able to pull a good vaccum and it held without moving for a couple hours. I then tried to put some r134a in it and the compressor wouldn't engage. Gotta troubleshoot what that's all about, but I hope it's simple. A/C work sucks donkey balls.

    I’ve got one installed on the driver side. Still need to make another set of brackets to fit the other. I’ll snap some pics eventually and post them. It’s ungodly hot plus I’m in the middle of selling my house and building another. Hoping to have functional AC after tomorrow.

    Had some fun at another double header autocross last weekend. It was hot, but fun as hell. I think it's time to get stickier tires and some better brake pads. Maybe install the 22mm front sway bar.

    Some of the worst other than the 6 series US market bumpers.


    Good news with that though is I have a fiberglass front Motorsport replica and a fiberglass rep rear euro bumper.
