New supra owner (with a few questions)

Thank you gents. Here are a couple of pictures of the car. As I mention I'm not a Supra expert so want to know if the engine and parts are stock..specially the thrttle body and Tps. The car according to vin is a 1990 supra turbo.

so did you repair the vacuum lines and redo your diagnostic codes?

Looks like the stock throttle body to me.... Who told you otherwise? Post the part numbers already... sheesh.

I did some manual reading so i now know somethings about my supra. In regards to the idle problem, I bought a new TPS and it fixed the problem. My main concern now is the car stalling without notice. One of the codes shows a bad AFM.. what are the symptoms of a bad afm?. want to make sure before I make a costy purchase.

Unplug the AFM and go for a drive. Just don't get into a race. If it drives close to fine then the AFM is shot (note: this only works on the 7M-GTE models).

There's more testing info in the TSRM, but if driveability improves with it disconnected then it's pretty much given that it's shot.

Thanks for the information. I ended up buying an AFM. car runs perfect. I wish I could find out who was the idiot who put this engine tho. So far I have bought the following.
1. new TPS
2 new recirculating kit for my BOV
3. new AFM
4. New CPS dust cover and gasket(cps had been exposed due to a broken cover)
5. New vacuum hoses.
6. New universal Oxygen sensor

one problem remains; the car shuts off without notice, then it start right up it has happened 2 times while cruising on the street. I don't have any codes in my car so I don't know where to start.

Dying while the throttle's open, at tip-out or at idle? Stumbling or just smoothly cutting out? Have you checked all grounds and power connections (including at the ECU)?
