Heres a whacky one for you, 99 GMC gremlins ??
99' lowered stepside sonoma 2.2 manual.
Ok, I'll start from the beginning. Ever since ive had this struck, it is a hard start. So for example, hop in to go to work in morning, truck fires right up like normal. But once you drive it, and go to restart it, it cranks for probably 10sec and i'll hit the gas and its sputters and starts. Kinda like trying to start a carburetor car when the carb or choke is out of adjustment.
Seems like 9hrs is the magic number. Once the truck sits that long, it seems to go back to normal for that first start.
BUT! When its raining, or wet out, it fires right up ALL the time, just like a normal truck would. 2sec crank and start.
I changed TPS, and IAC. No improvement.
Ok, thats the first gremlin.
Next, when cruising on extended trips (trips farther than my daily commute) 25mi+ I noticed my batt light would come on.
I tested the batt with the truck running and all acc's on, and was getting some 13.4 and around there. So, I threw a new alt on. (the old one had a slight squeak anyways) (I also installed a new heater blower motor at the same time, cause the old one was going out)
Now NEW PROBLEM. During my daily commute, after the truck warms up (about 5mi's) the truck cuts out on occasion. And its almost always during a left turn, or coming out of a left turn. For instance, i'll be coming up to a left turn, i'll pop it out of 4th, brake into the turn, down shift into 2nd or 3rd (depending on which turn) and immediately upon pressing gas, it cuts out. It will cut out all the way getting into the 4th gear. But eventually clears up.
It is almost a perfect guarantee to happen on a left turn. It has happened ZERO times on a right turn (ive tried!). It has happened at a 4way stop going straight only a couple times. Stopping, getting into 1st, going straight, and cuts out all the way up to 4th then clears up once rpms get up.
I just couldnt drive it like that, so trying diff things, I threw the old Alt back on it. And the cutting out was not eliminated, but reduced by probably 75%. Its atleast manageable now.
So, the latest things ive tried. I'll go into a left turn, pop it into 3rd, slowly accelerate and it starts cutting out, so I turn the wheel to the right and every time ive done that so far, the cutting out STOPS immediately. Every time. wtf
