I have the base LX sedan, SPI engine, auto transmission, 85,000 miles.
I have changed plugs/wires/coil/PCV/checked for vaccum leaks and found none/changed EGR valve/DPFE(EGR) sensor/used fuel injection cleaner/changed fuel filter and still no improvements.
You can floor it and it refuses to accelerate at first but slowlp picks up steam and moves after a few seconds. It stumbles badly upon acceleration and goes through 1/4 tank of gas in <20 miles.
Ayy suggestions what else to check? I would suspecting the catalytic converter (maybe) but there is no sulfur smell/smoke from the exhaust that is abnormal...
I need to pass emissions this weekend too. Thanks :)

Forgot to add, I cleaned the MAF with quick drying electric cleaner but I will try a new MAF sensor as well....thanks :)

I put in a new MAF and it is slightly better but still stumbles/hesitates at times...at least it doesn't die on me. I also put in new ford plugs/wires/coil for good measure and it is still acting up....any more suggestions? :)

OK guys (and gals)..
took it to my local shop, they had me do a new MAF sensor, EGR tube, and induction service +plugs/wires/coil/oilchange for good measure. The light went off for a good 20 minutes after I left the shop but now it's back on. What next?

Also the fuel pump was replaced under recall last year and there is no misfire right now (flashing CEL). It runs beautifully, but there is still a CEL. I will take it to autozone and come back with the codes...

I would suspect the MAF or an upstream O2 sensor, but without a good scantool to see the live data, it's hard to tell. The stumbling bad on acceleration leads me to believe it's a bad MAF sensor.

Cleaning the MAF with anything could have damaged it. Start there, look at O2 sensor and the coolant temp. sensor. The other reply is correct, without a live scanner, hard to say.

Your fuel pump my have a problem with keeping up to pressure demand. You could possibly have a M.A.P. sensor problem which measures the amount or air entering the intake.

try changing the inline fuel filter or it could be the computer chip

Make sure you didn't cross-wire the spark plug wires.
