ive replaced some vac hoses, idle valve, checked tps ok . i have two mafs. maf 1 over fuels car stutters but drives ok , suttery. maf2 drives good hangs revs everywhere. either they are both fcked or maf1 is masking the rev hang by over fueling. or maf1 works and something else is causing the overfueling.
need to check the intake temp and coolant temp sensors.
