As the title says, my 1J will not rev past 2400rpm. It consistently stops at the same rpm. The idle is lumpy and the computer locks me out from any higher rpm. I was thinking MAP sensor? Anyone have any clues?
It stumbles and tries to keep revving past 2400. I actually got it to 3000 last night as the sun was going down, but it reverted back to the 2400 cut-off after that. I'll try to find out how to check all the sensors mentioned. I think its overfuelling a shiteload too - maybe fcucked FPR or stuck open injectors? Where is the FPR located?stroker said:Your "whirring" sound may be your power steering pump or a intake manifold leak. Where is your idle at? You say your getting gray/black smoke out of the exhaust? If your try to rev it does it hit 2400 and then fall back to 1000 and repeat or does it stumble and try to keep reving in the 2400 range.
