Just went to Ace for some LP gas, and runs fine now. I did do a quick throttle relearn (waited about a minute), so not sure if it was that or a cool down sitting an hour in 30 degree temps.
I have suspicions that the IC pump is flakely, it is an OEM unit. But I have never heard of the IC pump effecting off idle throttle for normal driving. Seemed to be TPS or APS related because slow movement of pedal in neutral up to about 1200 rpms resulted in some strange responses, almost like a sporadic dead spot. Is not doing so now which is weird!
Once I get it put away for the winter, have a list of things to go through on it.
If anyone has any insight (been there, done that), please chime in.
