Bogged down While In Gear And Sputtered During Acceleration

Thanks for the replies, they are greatly appreciated.

The reason I keep thinking it is a trans problem is because the engine runs fine until put in gear, but now am leaning back towards the engine. No overheating, no missing while idling or revving. I got the gas that is in it now the day before the problem happened and drove about an 1/8th of that tank that day with no problems.

I'll check the fuel pressure today. I do know the tank is cruddy and regularly change out the fuel filter. The mechanical fuel pump has less than <1k on it.

The new timing chain and gears have <1K on them. If it were to skip a tooth wouldn't the timing at idle be off too?

I have a Mopar Electronic ignition (Orange Box) and distributor that have about 2k miles on them.

I don't have much for a trans/converter history. They came with the car 3.5 years ago and the fluid has always looked good over the 4k or so I have put on them . The filter and pan weren't too bad when I changed it yesterday.

Thanks again
