Thread: Intake temp vs coolant temp.

It says MAP, which is manifold absolute pressure. Which should also be measured in kPa.

You could easily have issues with the MAF being dirty/out of spec, old plugs/wires, weak coils, dirty fuel injectors, weak fuel pump, clogged fuel filter etc.

It could also be transmission related as well.

That's true... I did check fuel pressure its about 45 psi. I cleaned throttle and have not been able to find any intake leaks. Tinkering with the maf wires didn't help either.


When I unplug the maf sensor (which is a fairly new aftermarket unit) it doesn't hesitate and it has better pick up.

But I know that unplugging the maf doesn't necessarily mean the maf is bad, because unplugging it masks other components that could be the problem.

In the next week I'm going to try to do a tune up, and clean sea-foam the injectors. And see what happens.
