Serious Help with CODES?!??? Car stumbles when heavy accelerating until you let off the gas. Sometimes will just die going down the road. Idle is good for 5 secs at a time then stumbles 1 sec then back. I have no engine mods. I did the TB bump stop mod and TB bypass mod.
Did a drill mod, flushed clutch master cylinder, replaced plugs and wires, replaced fuel filter, electronic cleaned MAF and fittings, tightened clamps on induction, tried to reset CEL, didn't work. Also have a new accessory belt. My new plugs and wires helped out with the bad idle and stumbling. I'm pullin codes:
P0102 MAF or VAF Circuit Low Input
P0103 MAF or VAF Circuit High Input
P0704 Clutch Switch Input / Circuit Malfunction
I got a new switch for clutch also and I'm still getting these codes.

Ok unplugged battery, codes gone. Codes back on, P0102. Car stumbles at idle goes below 500rpms and sometimes gets back up or dies. Mostly dies. Feels like no gas is getting to it but there is because when it stalls I pump the gas and I see it go out the pipes... yes I know its smoke. Looks like the maf. I also did the tb bump stop mod and volts are at 4.68 but if I mash really hard the volts go to 4.74. Will this throw a code.
tps & maf don't have a relation in this case, its your maf thats probably causing the issue, swap it with a good one to see if the condition goes away. If it does you know you need a new maf.
