i blew my motor and threw a 5 speed in as well. now when i rev it it acts like its hitting a rev limiter or fuel cut off at 2500 rpm. wtf is wrong.
also i deleted every egr and emissions item i could including pcv. i welded the ports shut. so i dont think it has a leak.

sounds like mafs man. Usually when theres something wrong with the mafs, it goes into a "safe mode" or something that usually won't let you rev past 3k or something. Check the wiring.

yeah that sounds like its in safe mode. Swing down to Oreilly's and have them put that shiznit on the code reader.

Easiest way to find the problem.

k well i got a p1105 code map / barometric pressure switch solenoid valve do i need to fix this too?
p1441 ev/v bypass valve which i think is just emissions
p0105 absolute pressure sensor circuit wtf is this?
p1605 a/t comm line yay no more a/t
p0100 mass air or volume air flow circuit this is probally the culprit
and a few more evap system codes. should i be worried about any of the other codes. trying to troubleshoot the mass air system now

MAFS. Find someone parting out there 240 and buy they're MAF, because a new one is EXPENSIVE
