not sure if this will be of help: http://www.suspensio...scon/1130t.html

Very interesting post, thanks for the thoughtful reply. I have already done most all that I can do with a comprehensive tuneup. Adjusted the valves, new valve cover gasket,end plugs, PCV & gasket, cap, rotor, spark plugs and plug wires, timing and idle speed adjustment. Replaced all of the vacuum lines and hoses, oil filter, synthetic oil, trans filter, gasket, synthetic trans fluid, differential fluid change too. I still have the fuel filter to change out, brake lines to flush,, and coolant flush to complete. The other thing I want to do is the throttle body reconditioning that I was reading about on this forum. I am glad to hear there is nothing unusual about this condition, as I was worried there was something catastrophic going on. I drive and do my own work on an Audi allroad which is a great more difficult to get things done on. I love working on this thing, it is my first Toyota ever, and it really is nice to be able to get at everything. Again thanks for the feedback ............ Brian

I am a new owner of an 85 Toyota RV. It has the 4 cylinder FI engine and the auto-trans with over drive. I have some concerns regarding it power or torque, not sure which and I am wondering if someone can help with determining what the actual problem is. Here is the symptom: when I slowly pull into my uphill driveway and am careful about bottoming out and my rear wheels are up against the curb stopped, I cannot get the RV over the curb and continue uphill. I can floor it and the engine will rev some, but seems to bog down. It revs fine in neutral, but when I put it in drive and give it gas it goes no where. If I back away from the curb and get it rolling forward I can manage to get beyond the curb and up the driveway OK. I had the same problem camping, I needed to turn around, I was on a dirt road, and headed into a field with a moderate down hill grade, gave it gas in reverse for the turn around, and it did not deliver the power needed to back up the grade, took three people to push her uphill for the turn around. Highway travel here in Colorado has been OK, I have managed to maintain speeds on mountain passed, although not the most severe, managed Monument pass at speeds of near 45 MPH. So if I have momentum everything seems fine. It is all about the ability to manage grades from a stopped position. Any feed back would be greatly appreciated ............. thanks ............. Brian
