no luck guys with cleaning the MAF..but after furthur inspection i found that my timing belt has about a 1/4 inch missing from the front side of it and is frailed out..also looks as if the cam gear on the passenger side is setting about two teeth ahead of the driver side gear..could this be my problem lol? also does anyone have just a quick instructional walk through of the timing belt install..need help as to where i align the crank..after searching , i seem to have read to place both cam gears at TDC (marks on the metal casing below the plug cover).dont mean to sound like an idiot but i wanna make sure i do it right the first time..lol..PLEASE HELP..
You may want to check your engine timing at this point. The crank pulley should be at 10 degrees idle when your car is warm (you will need an engine timing gun). Judging the condition of your timing belt and cam gears, it may be a good idea to get this changed out and re-time the engine.
This come be the reason why you are getting alot of black smoke at idle, because the engine is off on its timing. However, it may not necessarily solve your problem with the engine dying at idle. You may want to check if your dash pot (behind the throttle body) has some tension on the throttle linkage. It's possible that the dash pot may need to be replaced, because if the idle drops too fast it can kill the engine. However, its rare to see a bad dashpot and this may not be necessarily your problem with the idle dying.
As for the engine timing. You can try and just retime the engine at 10 degrees before your change the timing belt to see if your Supra runs better. However, judging the condition of the belt and the cam gears being off, you may not be able to get the car time properly. But might be worth a quick try to see if the engine timing is really causing your problem.
