Btw i believe the ecu after a disconnevt , learns up until the coolant temp reaches normal or turns on the fan. It may hunt at idle and flat spot a bit until it learns you may have to coax it a bit.
Also initial suspicion is airflow meter may be faulty or low quality.

(Solved mine)
Well i worked it out .
when they fitted a second hand engine to it they changed the timing belt and crank seal .
dun dun dar they broke a tooth off the crank cam pulley. (Making the ECU think it has two TDC )
why this makes it kill spark to coil 1 and 6 and also kill the injection for 2 and 5 .
who knows but mine runs sweet now

A theory
Well i had a thought today .
i put the crank it the location so the missing tooth was inline with the pickup and it is very close to been the firing point for coil 1/6 which might also be the point the ECU uses to time the injection for 2/5 .
just a thought

Same Same
Bought an 01 gs300 with a bad throttle motor. Had all the codes cone up, tps, pedal sensor, and throttle motor malfunction. I found a good one on eBay, so I just changed the whole throttle body. Anyway, car fires up, no codes, but will only idle for about 3-4 min. If I try to give it gas, it hesitates, and pops through the intake. I have replaced the crank sensor, cam sensor, timing belt, fuel pump, etc. car is in really good shape, this is driving me crazy. Timing is dead nuts, and like I said, no codes. If I pull the batt cable off, wait 10 min, it will start again, but does the same thing. Anyone have a clue as to what's going on???
