CEL is back.....help

[John4cam]

yes and sometimes no it will stay on until i am off the throttle

I'm sure someone will correct me if im wrong but I always thought a blinking cel is a missfire in one or more cylinders. It makes sense too because it only seems to happen when you have the car under load, and not in neutral.

Ageeed. A bad O2 or somenthing like that would cause a steady CEL - not a blinking one.

could be the other 02 sensor that is the most common reason for check eng light on older cars , any chance its a vac line to egr or things in pass fender?

Troy,
wouldn't that be a steady CEL instead of one that comes and goes depending on the load?

it doesnt missfire cuz rpms climb steady on a hill in 4th

well new TPS, cleaned IAC, and new o2 sensors......still comes on and goes away....doesnt do it as bad but during startup and the first few moments of driving it doesnt do it.....so i am running out of ideas

Most if not all OBD I cars don't set misfire codes. The car should store the code even if the light goes off. Get it scanned.
