Hi all, I'm new here and finally got approved for posting! so here goes with one of my biggest headaches. My 87' DL purrs like a kitten. Starts right up every morning. I've had very few problems with it in the 3yrs I've owned it. I replaced the drivers CV joint, and besides regular maintenance I havien't had to do anything to it. The only complaint I have, and I'm not trying to win any races its a total cruiser, is that when accelerating, Pushing on the pedal causes the engine to bog down. Kind of throws me FORWARD in my seat. Playing with the pedal a little to find the right spot get its to go again but its really frustrating. A friend and I were poking around and we were looking at the EGR valve and the PCV valve but I have no clue as to how to check them. Ive tried looking through on here but there is alot of info on here so I thought posting would be a good idea. Also, after driving and stopping, the idle will be high, but if i tap the pedal it kicks back down. Saying I am an amatuer mechanic would be boastful. I am an extreme novice at best. Any help would be greatly appreiciated. Also soon I will upload pictures of my baby, little Red I call her. Thanks again in advance.
