i dont know what in the F*** is going on. my car keeps randomly dyin on me. itll hesitate then die or sometimes correct itself. i took it to the shop and he cant figure it out either. we though it was the wires near the ecu because the idle was fucked up(hunting) then we played wiht the wires tryin to see if we could short it out and make the car die. it would die sometimes but miraculously the idle was normal. but still hunts a lil. i just got the car back he said the cars hasnt given him any problems and he been driving it around for and been runnin for 4-5 hours. nothing. well i drive it to work and it started to hesitate again. i need help.

Who did the swap? Is your car throwing a code? Check all your vacuum lines, TB sensors/connectors like MAP and TPS, sensors on the IM itself, look inside the TB to see if its dirty or if the Butterfly is getting stuck. What year is the LS also?

 

i bought the car after xmas and the swap was done in june. no codes are being thrown. and the motor is a 94 LS obi 1 motor. mmm ill have to see what i can do about the video. me and my friend checked the butterfly and all that. everything seems fine. cleaned out the IACV and the other part that controls idle its n the tip of my tongue. when i bought the car it drove like a dream. and the couple weeks it died on me randomly. i thought nothing of it you knownow it just does it more often. now wen i did buy the car the only problem the guy said he had with it is that something went wrong with the relay and had to replace it. and i have an extra relay. my mechnic brought in a electrical guy and they said the relay was gettin hot....

 

Check your vacuum lines and oil pressure.

And get your swap tuned.
