1993 Travelaire 454 chev p30 low power
Last year, I purchased a used 1993 travelaire 34' class 'A' MH w/t a chev 454, (TBI i believe) and has the 4 speed A/T. I live in western Canada, and have since made several trips into the rockies. I've never owned a class 'a' before, only an older class 'c'.
The biggest issue I seem to be having is lack of power, and that's where I'm looking for some assistance.
At first, I thought the issue might have been dirty gas. I replaced the fuel filter located on the frame (It was extremely dirty). I then ran a few cans of Sea-Foam through it, but no change in power - or very little.
The MH has 58000 kms on it (about 36K miles).
I realize this is a large machine, and GVWR i believe is 16000lbs, so it will not accelerate like a car, but it takes about a full minute to reach highway speeds (65-70 mph).
I've changed the cap, rotor, spark plugs, wires, air filter. A point worth noting - the engine runs perfect otherwise (no stumbles, misses, pinging, and starts perfect each time).
I have not checked compression.
It would almost appear that the engine is starved from fuel from what I perceive to be a lack of power, esp going up hills (at those times it also heats up and borders on going to red).
This summer, I would like to be able to tow a trailer behind, but not with this low power.
I know that a lot, if not most ppl will call BS, but this also seems relevant, my gas mileage is, in my opinion, absurdly high- 17.5 mpg (imperial gallons) averaged over 6500kms, that includes mountain and prairie driving.
My last MH, only 24 ft w/t a 350 chev had a ton more power, but only ran a best of 9 mpg. This is why Im thinking it is a fuel delivery problem.
If anyone can offer any suggestions, it would be greatly appreciated.
