k Here it is. My car ran fine for liek 2 month and now this just started happening. First it would rev hella slow and wouldmt move fast if i got on it. Now if i start it, it runs fine for 20 secs at idle than it drops to 700 than 400 than the car dies. My a/f siad it was running hella lean too. Any idea's?

Have you changed the fuel filter lately?

Checking for vacuum leaks and error codes in the computer is a great place to start trouble shooting.

i checked for vac leak and i chagned the fuel filter. i chagned the fuel pump too and still the same. i got a 70mm pro-m for my 24# injectors to. what would happened if the pro-m was bad or the fuel pressure reg? maybe the injectors r clugged. when i put it in gear and start going its starts off hella slow and seems like its going to die but once i get into third it runs ok intell i start to slow down than its drops to 400 and i gotta break and rev the motor at the same time

do you have another mass air meter you can swap out to test the pro-m.
sounds like the IAB might be boogered up. take it off and clean it.
did it start doing it when you added the new mass air, or did you put on the mass air to try to fix the problem?

No, the pro-M has been on there for a few months. I also pulled the mass air plug and wires to put the car in "default" mode and it still ran like shit and died. So you think the IAB might be clogged? Seems reasonable to me. This one has probably never been cleaned and has 100K+ on it. Do these normally need cleaning after 100k miles?

Does it have cats? Sounds like they are plugged.
I have seen cars towed into the shop that wouldn't even start due to restricted exhaust
