Hi everyone, new to the forum but I've been having some issues with my fj62 that I was hoping I could get some help on. I have a 1988 fj62, I took the car in to have the fuel pump replaced and when I got it back it had issues with the idle and stalling. The car's idle can be consistent at one time and at other times bouncing around between 500-1000rpms. In addition to that, sometimes when I back up my car completely stalls out and shuts off. My engine also stalls consistently while driving. I almost forgot this last part but the car also shifts late. All problems I hadn't experienced since I replaced the fuel pump. Any thoughts on what this might be and how I might go about fixing it? I'd upload videos if I had and if it happens I'll get it on video. Thank you guys!
