Ok so I have a 99 gs with a 420a motor. Which I swap for a refurbished one. 2 years ago. I've had the car for 3. Sense the beginning I've had a engine code for a confirmed misfire. And 4 pending codes for each cylinder. I have done basic tune up and changed all my fluids. Even changed the ecu at one point. When I blew the motor it came with thats when I got the refurbished motor. And I continue to still have these codes I have changed about 90% of sensors you could think of and fixed a few parts of the wiring however the codes are still there you can read the codes off the car but in terms of communication you won't get much out of it. It happened with both the old ECU and the next one I placed in. Nothing I've done has worked so far so maybe anyone here can help me.
I have a 99 gs with a 420a motor. I've had for 3 years along with certain issues. Recently in the past month when I raise the rpm past 4 my car started to hiccup or sorta backfire. And it only have 4 rpm and up, it doesn't happen when I release the gas only when I have my foot on the gas. I have no leaks. Or vacuum leaks. And my sensors on the intake are changed. Nothing comes up on the scanner for any sensor issues so im unsure what it could be.
