i got a 1993 chevy 4.3 tbi rwd automatic. will start running bad after warming up and acting like its starving for gas or something but i hit the gas and sometimes it will level back out . and also happens when i put it in reverse or drive it happens also. It wiill also run fine on the street (sometimes) but when i start to break it starts to stall or something and then once i stop its fine again or ( sometimes) will try to pull me through the light. no engine light either. i changed a bunch of stuff but idk could it be a ground? ran good all summer tho besides the hard starts but always started. If you guys got any idea's post them pleasel. Thanks!
