14.098 at test and tune
First pass was great. Ran a 14.098
After that the car started running like sh*t. It actually ran better with the MAF sensor unplugged (but never a 14.098). Check engine light was coming on , then going off sometimes...
Seems like the car was shutting down my acceleration past 4000 rpms...

If that MAF sensor is bad grab a reman at Autozone asap, make sure to replace the maf burnoff relay at the same time .
Mine had done that intermittently,(98% of time time it was fine) displayed no codes. By the time I figured it out it was too late, MAF made it run SUPER lean and ate up a head gasket over time .When it acted up at higher rpm it "bogged", kind lof like dragging the brakes. This was over a good period of time, wouldnt sweat it if I were you. not saying this will happen to you, just dont let it go.

With bad MAF
Check out the A/F ratio
That thing shouldnt even be running. Come to think of it, it almost wasnt.
Changing the MAF, burnoff relay- no other changes at all

Is your car an automatic? What were your trap speeds?

I'm assuming you're asking about the fuel filter, I've never changed it.:o
Appreciate everyone suggestions, I'll be checking it out tomorrow.
Drove the car to work today and noticed the low coolant light is on, too.
