As the title states I have an issue with my 94 4runner 3vze automatic where it just dies when it’s on the trail and goes over a bump. I’m suspecting a bad connection but I don’t know where to start. Then it has a hard start afterwards like it won’t catch. I spray carb cleaner or fuel in the intake then it catches quicker. I can drive around town without a problem. I replaced the fuel filter thinking it coul be that and I don’t know if it was ever replaced. I also had a code 22 for ect signal performance and turned out the previous owner had broken the ect sensor connector and cut the harness connector off. I can hear the pump run when I jump it in the diag port. When it dies it doesn’t stutter or anything it just slows down and turns off. Sorry if it is too much but it’s my first post and I swear I searched the most I could and well I made an account because I can’t figure where to start. Any help is appreciated thank you
