CEL only below 1500 RPM

[ars14]

I thought it was the same as the sticky post, but I dont think so
if I drive and keep the rpm above 1500 its off but as soon as I drop below it comes on, then goes off after I accelerate, I cant get the ecu to respond with any codes. What could this be, TPS or Colant sensor?

Help

not sure, oil pressure? dont know, guess youll just have to go faster and always have it in gear

This is what my XT used to do, until I replaced the O2 sensor. I know this is an EJ22 that we're talking about and not an EA82, but you could give it a shot...

Thx all I was able to pull the codes last night and got knock and O2 so I guess its time to get a new one
