Afternoon Sports Fans, new member. Just bought a 95 Pickup/4x4/EXT CAB/ 22RE no CA emissions. TRK has a secondary used ENG that was put in couple years ago with 80K+ miles on it. TRK has been sitting for the last year. The TRK has some issues the previous owner didn't want to mess with so I am trying to figure it out. He swears it ran fine and he showed all his maintenance records showing all he had done since owning.
Since he had the O2 sensor replaced he said it has ran different and he got tired TS it. When I got the TRK this is what it does and still doing, but not as bad. The problem is when the engine is cold, it runs fine, then as it starts to warm up, it starts surging, once it warms it it stops surging, but starts looping or missing, turn on the A/C and it smooths out. It kept getting a OBD 1 code of 25 (O2) I confirmed and replaced (someone had installed wrong one) the surging got a little bit better, then started doing same thing, than got a code 71 (EGR) I replaced EGR valve as it was clogged too bad to clean. I have cleaned the whole EGR and vacuum system no leaks or bad hoses or any other bad part that I could find. But once changed the EGR Valve, it is a bit better but it still does the same thing not as bad or all the time, also get a valve lash/clattering sound sometimes while driving but not all the same condition driving, none while idling. Any suggestions. Timing/plugs/wires good. No oil or water burn smoke off/loss.
