this is a fuse I honestly believe check them with ohm meter. Lots of cars if you have a tail light out the dash light will not function also. I hope this helps

My 97 Jeep Grand Cherokee was doing the same thing. I changed the TPS ( Throttle Position Sensor) Now it is great goes into overdrive fine. It is really easy to change.

SOURCE: diag code 21 94 jeep cherokee
Error code 21 is oxygen sensor or circuit.Check the oxygen sensor first and then the circuit. The sensor is on the exhaust manifold or on the exhaust downpipe.Its purpose is to measure air/fuel ratios and adjust the fuel that the injectors deliver.Above 80000 miles is the sched. to replace this sensor. Hope this helps

Not a tune up problem,
You need to have all U-joints checked out,They will give you the vibrations only while acceleration
