I have a 1992 Lexus SC400. Had the timing chain, water pump, tensioners, etc. replaced as well as the coils, distributor cap, one of the rotors, wires and plugs replaced as well. Car ran great. Got in it to crank it up and it would crank up and fall dead. I checked the MAF, still nothing. Happened to crank it up and left my foot on the brake and it starts and stays running. As soon as my foot is almost off the brake, it falls dead. I spent all day today screw with trying to get the MAF screws off to replace the MAF with another one. Does anyone have a clue what the hell is going on with this car. This is my first SC400 and from the looks of things, my last. I'm getting frustrated with this car. Let me know, thanks in advance.
