hello everybody i'm new on here and need some help. i have a 1993 s10 2wd automatic with a 4.3 in it. it ran really strong and shifted gears really strong like it had a shift kit in it. i could floor it in overdrive and when it shifted it would bark the tires. well my g/f wrecked the truck and we put it back together but now when you pull out and it shifts gears its like it just boggs down. you can mash the gas on down and it will go on. not a major problem just gets me . it has a new fuel pump, fuel filter, new plugs, distributor cap. some kind of sensor(forgot what it was called) thats on the passenger side of the tbi or whatever my truck has. its doesn't have a carb. thanks for the help.

How bad was it wrecked and what was done on wreck repair?
Any codes?
Check engine lights?
Engine or transmission?
How is fuel pressure?
Has timing and engine vacuum been checked?
What is engine vacuum readingf at idle and at 2K rpm?

Is it upshifting to quick?

What are up shifts speeds in MPH on a normal take off?

mostly cosmetic damage we just put the front end off another s10 on my truck so nothing as far as the motor or anything was touched. no codes, no lights, fuel pressure is good, all the vacuums are good, haven't checked the timing yet plan on that this evening. it still shifts normal but i think around 45 to 50 mph is when it just boggs down and like i said whenever you press the gas on down it will just kick into passing gear and go on and its mostly when you go uphill.
