Jamaroon's S10 ZR2 Trail Rig
If you ever have issues like that again with the loss of power and stumble and everything like that but find that it isn't the o2 sensors like I did, it is going to be the fuel pump! My pump was fine until the truck warmed up then the pump would overheat and only put out a bit of fuel and I had the EXACT same symptoms as you! Checked both o2 sensors and they were in great condition, checked the fuel pump multiple times but never thought to after if had warmed up so I got lucky finding that out! But yes, hesitation, lack of power, after awhile it would die and upon restart I could only do about 25-30 mph and never above 2000 rpms, glad your fix was MUCH easier than mine!!
Appreciate. Sucks cause this forum got blocked by work and I kinda forgot about it since I am hardly ever online otherwise. Now I can get on and my build thread is locked and I cant update it. Only been a few years...
