The 1991 MR2 Does not have a Mass Airflow Sensor, lest it be added aftermarket.
So your issue seems like it should be solved by overhauling the engine.
entails cleaning everything out, from the inside to the smallest valve, that will fix it.
Make sure to check all belts (timing, serpentine) for tears or the like, remove the valve cover and check to see if nothing is jammed. If you are not gear savvy, ask a mechanic in your area to come take a look at the engine, there could be something more amiss here than just a faulty valve cover or a stuck valve.

2002 impala 3.4 crank no start, no check engine light, or security light besides the one by radio that flashes

Hi Jarrek.
Since you had to pulse the injectors to start the motor its possible your camshaft position sensor/crankshaft position sensor is bad (More than likely your Camshaft Position Sensor). Another possibility is your MAF (Mass Air Flow) sensor may be bad, going bad, or just dirty. The parts store sells a cleaner for the MAF sensor. DON'T clean the sensor with anything else, it will damage it. Hope this helps. Let me know.

Yes the mass air flow sensor is tied to the trans module and is used in the calculation of the shifting points. I would change the MAF. I have ran into GM cars with MAF sensors stalling engines. Those years were notorious for it

Hard too start when cold

A lot of times when the car is hard to start when it is cold, it is the mass air flow sensor causing the problem. On the newer vehicles the mass air flow sensor acts as the older choke worked. It limits the amount of air flow. Which will make the engine start faster and easier.

starting definately has a lot to do with the crank/cam position sensors, but it wouldnt have nothing to do with hot or cold weather, oxygen sensor will make the vehicle run too rich if its out, you will smell fuel very strong out the exhaust, that could make it run sluggish also, and usually if the mass air flow sensor goes out the vehicle wont start at all...

Replacing mass air flow sensor in 97 vw jetta

If the mass flow sensor was bad, the check engine light should of came on giving off an engine code. To remove the mass flow, disconnect battery neg cable, then pull of the wire harness and pull out mass. You will probably have to remove the air intake hose.

Changed Mass Air Flow sensor, CEL still displays problem

it almost sounds like a fouled fuel injector. this is a tricky problem because it involve so many different operations. the maf is used to deliver fuel and the o2 sensor tells how much. there are 2 o2 sensors one before cat 1 after. mabey check these out visually. the computer should pick these sensors up if there bad. is this a supercharged engine? ill try to come up with some other ideas for you soon.

1999 pontiac grand prix . will not run

If you unplug the MAF sensor it should run using the default mapping. I'm having the same problem, but I want to figure out why it won't run with the sensor connected.
