93 ranger 4cyl, 2.3 dual spark

it starts, runs, has no power at all it is dirt slow, it seems to have a small surge but barely noticeable. I cant figure it out

is the check engine light on? Did it just start doing this out of no where? Plus those truck are slow ass shit anyway i have one haha

On my mustang it did that, and i just bought some MAF cleaner and cleaned it off, ran perfectly!

Check compression yet? How many miles are on motor? Had to pull a car into the garage one time that had blown motor, ended up having to push cuz there wasn't enough power to go up the hill, but drove slow as s*** on level ground.

dont have a compression tester, the truck starts and runs good just sitting and when i rev it its clean too, just absolutley no power, i was thinking about replacing the maf,

i just bought the truck and figured i would try and get it running good again before replacing the engine

could have skipped a tooth on the timing belt. So i would check the marks there a round plug that pops out of the cover so u dont have to pull the whole timing cover. Also the dis module with make them do crazy things

oh most of the time when the maf goes bad it will throw the light on and spark knock real bad most of the time

what is this sensor

91 Hatch

clean the maf sensor with air/intake cleaner. If that does not solve the problem, disconnect the downpipe from the manifold and try it with open header to see if the cats are clogged

Air fuel ratio is off if you get no power under load and little "surges". Check the MAF, air filter (no power under accelleration), and if there is any vaccuum leak at any seals (surges). Quick spurts of ether or carb cleaner around gaskets and seals will help you find leaks. If the engine surges when you spray near there, that's the location of the leak.
