Hi, i have a 88 body toyota with a 92 2.4 22r motor, i just got this truck it has a 4 inch body lift and is running 33/12.5/15 AT'S my problem is i can drive to work fine truck runs out great, but after sitting for 12 or 24 hours it is doing what i can to get to 55 and will burn about half tank of fuel to do that, it feels like it just isnt pulling through the gears, i have re timmed it ( was 33 degrees out) and put new plugs and wires, my next thing is to change timing chain and new fuel filters, other than the 12.5 wide tires what else could be killing the power of my truck ?
