I have an '83 Cressida that I just inherited. The car has 154k miles,
5MGE (2.8L) and AT. The car has been sitting for the past 5 years, started 2-3 times, and never driven during that period. I want to get this car back on the road. I replaced all the fluids, new plugs, cap, rotor, wires, air filter and fuel filter. The engine starts easily and idles very well. I measure 22" of manifold vacuum at idle (rock steady on the vac gauge), and set the timing to 12 deg BTDC and verified the ECU timing advance is OK. The problem is a significant hesitation, and loss of power when the throttle is opened. When in park, the motor won't stall, but attemtping to drive the car, it willl stall, and will not get above 20 mph.Anyone have any ideas as to where to start to diagnose this? I'll replace the O2 sensor, since it is original, and the motor will run better, although I doubt this is the cause of the problem. I may replace the TPS also, since it is also relatively inexpensive, and will also make the motor run better.
I don't want to replace the EGR or Air Flow Meter unless I am convinced that either/both will solve the problem. These parts are both quire expensive.
I sprayed the throttle bottle w/ Gumout to remove buildup.
Thank you.
