I recently replaced my Pathfinder's VG33E and I can't seem to get it to run correctly. I am getting a P0300 (random misfire) code but that's it. My main concern is not the misfire, but rather the TPS. In order to get my vehicle to run semi-close to what it's supposed to, I have to turn my TPS sensor completely to one side. I know that there's a specific procedure to follow for adjusting the TPS, but I have no option. If I even slightly turn the TPS towards the opposite side that it's clocked to, the RPMs will jump to 3000+ from the already high 1500 RPMs. To add to that, while driving the car's recognition of the pedal is intermittent. What I mean by that is sometimes the pedal is recognized, but then the vehicle stops recognizing that I'm still depressing the pedal. The only way to go around that is to put the pedal to the floor for a second and then let off once I'm at the desired speed. I should also mention that when first adjusting the timing, the only position to get it to run correctly was to again, clock it to one side but instead of the TPS it was the distributor. I have heard about a closed throttle position relearn procedure, could this be the solution? If so, please let me know where I can find it. Any insight is greatly appreciated! I am pretty desperate to get my Pathfinder running well again.
I have made an Imgur album to show you where the TPS is currently set at, as well as what my diagnostics tool has picked up. Since I can't insert a link, please put "/a/1Hbh8" into the address bar following "Imgur.com"
