Since it is raining buckets outside, I'm inside contemplating my current issue and reading my service manual (that's all kind of exciting!).
Since I installed the a/c compressor, I've noticed that there is a definite lag/hesitation when I push the gas pedal and when the engine responds. It feels like if I push the pedal too fast, that the engine will die. It hasn't yet, but only because I know slowly push the pedal til the engine rpms get higher.
The fuel system diagnosis for engine hesitates when accelerating warm says:
- secondary air valve sticking or binding (4bbl)
- vacuum leaks
- loose carburetor or manifold, leaky gaskets or disconnected hoses
- faulty ignition restricted exhaust
- distributor vacuum advance not operating
- idle transfer system dirty
- idle speed low or incorrect misture
Seems like there are many possible suspects given that I also replaced hoses and some of the vacuum lines.
I haven't driven it without the a/c on since its been so hot, so I don't know if this clears up when the a/c is off.
I also had a packrat chew threw lots of electrical lines which I've butt-spliced and heat shrinked.
It doesn't idle rough, it just has this late response to the gas pedal.
Fuel filter was changed 1 year ago in November.
If it quits raining today, what is the most likely suspect I should check? Or is there something I can try to rule out some of the possible problems?
Running non-ethanol gas in it. Was filled a week ago and have used 1/4 tank so far.
