Ok, at idle, my motor misfires every 2 seconds, and when i get on the throttle it consistantly hesitates and almost takes 10 seconds to get to 60mph from a dead stop.

Check all my plugs and all are grey/tan and dont smell like fuel.

Check all my wires for damage, none, even swapped them out for a good set, no fix.

Swapped air filter, and brake cleaner on maf sensor to clean it off.

Reset my ecu as well.

Fuel filter is practically new.

All injectors sound like they are firing normal when i listen with a screwdriver

I have fuel to all 4 cylinders

I have spark to all 4 cylinders

It is a stock, rebuilt KA24DE.

Idles at 1k.

Has a half tank of premium from Citgo.



Anyone have any idea whats going on?

My old KA did the same thing. Ended up being the MAF. Cleaning it may not have been good enough.

x2 It happened to me before, and cleaning it did not fix it, but another MAF did.

swapped MAF sensor, didnt fix it, gonna check the fuel filter again, i need a used one that is good, cant return a used fuel filter and dont feel like wasting 15 bucks on a test dummy

Holy crap just buy a new fuel filter. It's cheap insurance. Is the firing order right on the wires?

i just changed the fuel filter, thats why im hesitating on buying one that may or may not fix it...15 bucks is a lot for broke college kid

and firing order is right
