It could be a plugged catalytic converter or a fuel delivery problem. Check the fuel pressure under load. Remove the cat and inspect it. If all that remains is a golf ball size piece, then it self destructed and may have also clogged the muffler. Dennis

The idle is fine and power is good below about 3000 to 3200 rpms. Once I hit 3000 or 3200 rpms I lose power. This is most pronounced in third and fourth gears and goiing up hills. The timing seems ok; it is set at +/- 3 degrees btdc. I am pretty sure the ecu is good. I guess I can start by fine tuning the timing. It has new plugs, air filter, recent oil change and new filter. The fuel pump has been getting louder recently (last 3 months or so); I just ordered a new one and fuel filter (metal cannister type) for Van-Cafe and will install it when it arrives. Could this be a problem with the throttle body switch? I put in a new throttle body switch about six months ago. Any suggestions would be appreciated. Thanks, Sam |
