Hi guys,
I have a 1993 nissan pathfinder 4x4 se with 218000 miles on it. For a while now, it hasn't been driving the best, so I've replaced the air filter, done an oil change, cleaned the maf, changed the o2 sensor (found it through the codes), and just today changed the fuel filter. The car was running about the same or maybe a little better and the codes went away, but recently, maybe less than a week ago, it will randomly get super shaky (always been kinda shaky) and does not want to accelerate. It is loud and the car gets way shakier and struggles to gain speed but it kinda goes away once the rpms go up. It will stay for a few minutes and then randomly go away and become smooth again. I think I might try to get a video of this tomorrow and would really appreciate any advice. I know there's some other forums on here about this problem but most seem like it's a permanent problem and isn't coming and going like mine is. I think I will clean the throttle body and check the distributor tomorrow, but a mechanic should have replaced plugs and distibutor when it was takin in due to stalling issues about a year and a half ago. One last thing is, I could have sworn it's been happening more with the ac running since it's been hot here. Thanks a lot.
