Florin Posted October 26, 2011 Author Share Posted October 26, 2011 didnt you have the car the was jumping cam belt teeth? If I shift to 3rd quik then its fine it keeps right on going as long as its in gear its fine out of gear after pushing it a bit the rpm goes to 200 and dies . Not sure what else to put as far as info. Yes I did, changed the crankshaft gear and wheel trigger and new belt since then its been good hasnt jumped and idles great.

imi Posted October 26, 2011 Share Posted October 26, 2011 Idle valve Quote Link to comment Share on other sites More sharing options...
Florin Posted October 26, 2011 Author Share Posted October 26, 2011 Idle valve Where is it and how sure are you not that im questioning your advice just want to know if thats a hunch or.... I dont have the $$$ to just replace parts till the problem is fixed:) thats why im one here. In know that a lot of the guys that know their stuff prob get annoyed with guys like me. But ive been going blind and crazy reading up on the mkiv. Diff ppl say diff things and dont find very many "great threads" I mean they are all good to read but most dont have a bottom line "this want you have to do" type. I just downloaded 3000 pages worth of diagrams and pictures how to type stuff, but I cant read all of it in any shortish amount of time. I hope no body takes offence to this. But I thought thats what the site was for. I try! not to ask stupid questions and for the most part I think I havent. In the end me or some other guy who are I guess like the heading says newbies and I just cant spend 4,5 hours every night going tru old post or threads. Thats way I just tru a question out there after tryin to read up on my own but really Im getting to the point that Im thinking about selling the car just coz I cant really find the info I need and Im sure as hell not gonna pay some guy a grand for 2 hrs worth of switching some vacuum lines around and saying here ya go I fixed your car.... For the ones that have chimed in on my posts/threads ie questions lol I thank you very very much and If we didnt live so far away I take you guys all out for a round.

Thanks mellonman. Im gonna try that over the weekend its worth a shot just a cpl bucks for the carb cleaner if nothing else Ill know that the icv is clean Did icv clean, and it feels stronger but still dies after I push it hard and rpm dips down/dies. And starts right back up. Thought that maybe my mbcd is not set high enough but the things is im only hitting 15 at most on the gauge..... Also Im havingf trouble finding out where the speed sensor is, ( since its throwing the code) vss circut....A picture would be great!!! Thanks again guys.

tomgeer Posted October 31, 2011 Share Posted October 31, 2011 Download the supra service manual pdf, the speed sensor location is shown under the electrical components section. You can download the manual online (google it). If you can't find it PM me your email address and i'll send it to you. Quote Link to comment Share on other sites More sharing options...
