I swapped a 5 sp into a 1994 4.0 ranger. It has been running very rich. I had a exhuast leak at the manifold Y pipe connection and fixed that. There was a bad seal at the air box and intake tube and I fixed that. Truck ran better for a few days then last night it started running poor again. Stopped and got gas and checked mileage and I got 8.8 mpg on that tank of gas. Truck runs fine as long as I am able to drive out of traffic. In traffic or drive thru it lobes like it has a big cam in it and you can smell the gas in the exhuast. Still have the auto PCM in it but havent had the trouble in other 5sp swaps. Was thinking about fuel pressure regulator. What y'all think? What can I do to check it? CEL is on and off when lobeing. That was first full tank since put back on road. Truck has sit for 5 years
