My 3.4lt 2002 auto Prado Advantage towing a one tonne camper trailer does not want to go up hills - slows to a crawl - 1st gear on steeper ones. Without trailer, it's a faster crawl.
Fuel economy is18-20lt/100 km with trailer and best economy lightly loaded without trailer is 15lt/100km. No knocks, no backfires, no rough running, timing belt within service interval - tried all fuel types, injector cleaner, changed spark plugs, changed air flow sensor, cleaned air cleaner. No check lights.
The car used to consistently deliver 11.5 to 12.5lt/100km heavily loaded
I've checked brakes and bearings for temperature - all cool including trailer - checked tyre pressures - need to check wheel alignment. But I cant escape fact -- unexplained engine power loss.
Gave up and took it to Toyota. - Compression fine, all diagnostics OK, problem not found --- $260 please.
I'm now waiting for delivery of new fuel filter. But I'm running out of ideas
Any ideas?
Cheers
Chris
