Sluggish 20V Accel.

Ive had a problem with the acceleration in my 20v when i first put it in, and its seemes to be coming back these days. When i mash gas, it will gradually gain power in small amounts. untill its a constant good burst of power. I have no idea what that may be....bad gas from the pump maby? AFM settings?

Also i've been burning rich ever since i put in the engine and i cannot seem to solve that problem. The car seems to idle normal. I tried grounding the AFM, ive heard it helps but that didnt do the trick.....ANY help ?

now this may not be anything but the fuel filter is the correct 1 for a 20v? cause i had that problem with my old 4a but i got the right thing and it changed the accel.

It's not a specific 20V fuel filter, it's a regular parts place high pressure fuel filter.

I have had this problem with my AE101 Levin! I found 2 things. The airflow meter was faulty, which I replaced with 2nd hand unit and I removed the Cat converter (not sure what your emission laws are) and replaced the factory twin mufflers with a 2 1/4 pipe front to back with single performance muffler. Now gets much better fuel economy. Approx 450kms to a tank around town. Used to get 350ish. Also if you have disconnected check light that may cause problems aswel. Good luck!
