99 chevy tracker is running very rough, hard to accelerate
When I shift gears, it seems to run really rough and not want to accelerate. Sometimes it smooths out a bit, but then I have to change gears again. Anyone have any ideas? Spark plugs? How do we change them.

you need to let the RPMs drop down to match the speed you're going for the next gear, though this is less efficient than power shifting through.
Unless you're slipping the clutch to smooth out the gear change, yes, there will be a definite surge every time you grab a gear in a manual transmission vehicle. Most automatics will also shift noticeably harder at WOT.
For more sedate, "normal" driving, you can shift slower and feather the throttle a bit more to smooth out the gear changes, but when you're ******* the throttle as soon as the clutch engages, it's going to be a firm shift. I hope is ok.
Have you checked the fuel pressure under a load, low pressure will cause these symptoms. The test port is on the top of the engine in the fuel supply rail to the fuel injectors, the fuel pressure test port looks like a large tire fill valve. You will need a fuel pressure test gauge to do this test (about $20), the pressure must be watched while you accelerate, it should never go down on hard acceleration just up about 6-8 PSI
u need to have the system tested for trouble codes, but u most likely have a defective trans 1-2 shift solenoid. to replace this u will need to pull the trans pan off the solenoids are attached to the valve body, also check the trans connector for water or corrosion.
