replace your o2 sensor.... assuming your wireing is working well and intact..

 

bump for me

 

anyone? i think half of the problems would be gone if i got the correct usdm 99 gsr ecu but dont they have the immobilizer?

 

RESET your ecu and check the codes urself. dont waste ur time go n to autozone for that ****. if the car is throw n CEL for misfire, did u ever crank the car with the dizzy not plugged in? that will throw those codes. it could also be that the plugs r no good. do a tune up on the car (Plugs, plug wires, cap, rotor)

also when u did the swap did u install the O2 sensor????

 

take it to someone that knows what they're doin

 

i think i might need a tune up. anyone else with some good info? ill try reseting the battery also

 

is the 99 gsr ecu obd2b? and does it have the immobilizer?

 

sunday bump
