(94 sc300 180k )two days ago while stopped, in drive engine make a hick up or miss- almost stalled but I gave it a bit of gas and it went. 10 min later stopped and got out for 3 min or so, came back and it had stalled. Started right up and drove 40 miles home , no problems. Yesterday on the hwy about 80 miles into a 160 mile trip I feel the hick up- engine light comes on- I hit the gas a bit to go around a truck to get near the shoulder- nothing happens- thought it had stalled but it was still running just not responding to pedal. couple of seconds later it kick in. I drive the rest of the trip with no problem other than the engine light coming on and them going off a few seconds later. This happened about 10 times but no more hick ups. Today drove about 40 miles no problems, turn into a steep driveway to turn around and when I backed out the rear grounded a bit- not hard- parked and as I was grabbing a few things it stalled. Came out 1 hr later started and drove off but this time it was worse. It would hick-up- get engine light and not respond to gas. got it going a bit but then died. Started up but would not respond to pedal and stall out - over and over- unplugged the maf- it started and I drove it back to hotel- driving like s***. dark smoke coming out of exhaust. cleaned the maf, reset the ecu. drove it a bit and it drove like s*** but did not stall so I pushed it- it would pull then go unresponsive - then pull - same thing over and aver and then the light when out and it drove fine. parked came out 1 hr later- started up drove fine and 5 in later started the same thing. had to unplug the maf to limp back- recently changed the plugs iridium- 1000 miles ago- along with wires-denso- throttle body gasket- cleaned throttle body. new pvc- still using old pvc hose which is a bit cracked at the end but I don't think its leaking- any thoughts would be greatly appreciate as I am now stranded!!

 

wow! Thanks anyway
