New to Supra's had a few Q's - Page 3

Oh goodie.... There's always someone who just KNOWS they're going to be the exception to the rule. The 7M wasn't smooth enough for a MLS NEW from the factory! Why do people think it somehow must've gotten both smoother and flatter after 20 YEARS or service?! Good luck with that one. ROFL. Maybe you'll get lucky, but you're really probably going to be screwed in a year or less.

See the MKIII FAQ section for a thread on diagnostic/error codes. The problem sounds like either a bad airflow meter or serious boost leak. I hope he didn't try to clean the AFM.

There is NOTHING on the stock fuel rail that is adjustable... The Fuel Pulsation Damper (FPD, looks like a second FPR with a plastic cover) has a screw which is preset at the factory or a certain response time and pressure but it isn't to be touched under any circumstances (it's even covered in certain Toyota publications)... Touch it and trash it is the jist of it (really there are worse things to screw up with but you'll never know what it should be set to or how to do it Toyota doesn't publish that info that I've ever found).

Yeah I was real disappointed when I head an MLS went on, especially after I STRESSED that a composite be used. I saw the damper on the end of the rail but he was stating this was towards the middle of the rail, it's been a while since I had my hands on the car and I dont remember what was there. Thanks for the tip Ilook there and see what I can find

Nah, there's nothing in the middle of the rail really.... The cold start injector is in the manifold beneath it...

Do you know which brand and which type of MLS was installed? (If you say HKS stopper, forgive my laughter... and start saving to replace it in a couple weeks.)
