I need help with my 1996 ranger!

Ok I bought a ranger from a buddy he didn't need it anymore. Anyway it's a 3.0 2wd with a manual trans swap it runs fine and everything. But the problem I'm having is it's bucking and jerking in 3rd gear at mid rpm I can either let off the throttle a little and it will stop and do fine or I can push it to the floor and it will get out of the bucking it's doing and sometimes when it's doing the bucking it looses all it's power where I have to push in the clutch turn the key off and on real fast and then it's back to normal. This ranger does still have the auto computer in it so it does have some codes from the transmission not being an auto. The only other code it has is a cam sensor code. I'm just lost on this I bought a new cam synchronizer and it came with a new cam sensor witch I will install this weekend. But any help would be appreciated a lot!

New Cam sensor might help, make sure to set the crank up before removing old sensor, makes reinstall easier.

Clean the MAF sensor, it reports the air volume coming into the intake, this is the main sensor that sets fuel/air mix, if this sensor gets dirty, which it does, it can effect performance dramatically.

TPS(throttle position sensor) is operated by the gas pedal cable, it is on the upper intake.
These can get "dead spots", but these are easy to test with volt or ohm meter.

Never replace sensors, clean them or test them, sensors rarely fail, often just unplugging the connector and plugging it back in will get one working again, which is why people think the new sensor fixed the problem.
Also unhook battery's negative cable for 5 minutes, this will cause computer to reboot when started again, it will then relearn all sensor functions.
