I only drive my '94 80 series in the winter and just for pleasure . Recently while in drive mode (not OD) I felt a bit of a miss or shudder after coasting , but , it was slight and recovered right away with throttle input . On the weekend , driving back from the ski hill ,under compression , downhill following slower vehicles , (in drive) when starting to accelerate again up a slight incline , the Cruiser lost power and it seemed to be misfiring to the point that I needed to let the cars behind pass . After pumping the throttle ( afraid it would die ) it regained composure and drove up the rest of the hill and I carried on . I didn't see a check engine light come on .
Once down on the highway , I got it up to 60 mph and turned on cruise control . All was well until I hit the slight hill at the end of the potato field . Once again , it seemed to shudder and misfire , so I released cruise , pumped the accelerator and it recovered and I carried on .
On the way up the hill , in the morning , under power , it performed as usual . On the way down I had even passed a car and it was normal .
The cruiser is high mileage stock (mostly highway miles from PO ) , but I replaced the rotten exhaust with a SS header and 3" exhaust . I retained the two O2 sensors before I gathered the 2-1/2" down pipes into three inch main .
In the past couple years I have installed a new fuel pump , fuel filter , cap , rotor , wires and plugs . It sits all summer as I run the topless 40 .
Since there was no light on the dash , I thought that it might be a problem with corrosion in the cap or the rotor . I pulled and inspected them and the rotor had a solid coating of something gray on it that would not allow continuity from the coil (top of the pin ) to the end of the brass part of the rotor . I thought this was the problem , so , I ground it off . Once I got the new Toyota cap and rotor I noticed that this was a factory Toyota thing on the rotor . (It must redirect spark up the post on the distributor rather than to the side of the post ??) Now I really don't know what the problem might be .
With no light on the dash , there would be no code . Could it be an issue with a ground (intermittent problem ) , possibly a TPS related to drive (OD button )solenoid ... anyone had this happen ?
