Hey All, My '89 Vanagon has been sluggish, hesitating, surging and missing out when I press on the throttle (or accelerate). When I let her sit for at least an hour, she seems to do better and then once she's heated a bit she does it again. She has been sluggish when I start her initially also. I have replaced the fuel pressure regulator, fuel pump, fuel filter, spark plug wires, spark plugs, rotor, distributor cap, all that good stuff and she ran fine for quite some time then this misfiring problem cropped up when it got colder and I also have a leak where the oil cooler O-ring is so I bought a new O-ring and plan on testing the oil cooler for it's proper functioning and then reinstalling it with the O-ring and AMV sealant. I have been considering it possible that the fuel injectors are dirty so I'm looking into rebuilt ones and is there any way I can rebuild and clean these myself?? If it's possible is it cost worthy compared to buying completely rebuilt ones?? I was reading about the throttle valve switch being out of adjustment and possibly just bad, could this be the culprit? Another thing is that with this leak at the oil cooler I wonder if during the winter months especially if I should be using a single heavier weight oil than the 20 W 50 I've been using? Thoughts and expertise would be appreciated.
