injectors are fine
No leaks
New fuel and air filter
New TPS
New maf
New coolant temp sensor

Disconnected maf and ran fine without hesitating so bought a new maf thinking mine was bad. Its something that needs to heat up to work properly, so 02's?


Could be... Soon as it gets warm enough, it'll kick into closed loop and start using the O2 sensors... After awhile, they start getting lazy.

Don't think so...
From what you describe..it has to be something that works in "OPEN LOOP" but not in "CLOSED LOOP"

It is in "CLOSED LOOP" after it warms up..."OPEN LOOP" until the coolant reaches about 180 degrees.

It's either a leak, or fuel delivery problem...

There isn't a distributor cap & rotor to change :lol:


Also, I installed my Tekonsha P3... Now, time to find a trailer to test it on :lol:

I got all my interior leds from superbrightleds. If you know what you need, you can go there and find it, vs. just going to summit or where ever and buying a domelight bulb for $11 vs. $4

Today haven't did a thing

How do i check it? Cleaned up the o2's and that didn't help either. It actually started doing this after i installed a new radiator...
