i have a dodge carvan and my rpm is jumping and the speed is also jumping also and my engine light is on

Need more information. Is the battery good? Does it turn over? if the battery is good and it won't turn over you could have a stuck start solenoid (Tap with wrench) or the relay that energizes the starter is bad. I just replaced the relay which is part of a connector under the dash on my 98 SC2, after a new battery and an indication of no voltage to the started when the key was in the start position. works now

My 98 Saturn just did the same thing and it was the shift lever bushing. In this case the linkage felt like it was not connected to anything. Will need to put on hoist to see linkage to really tell.

If the clutch operation is good ( doesn't slip or shudder or allows the 1st gear selection ok ) then I would replace the clutch master cylinder as it may be catching in the cylinder bore or be binding up and leaving too much play and the shaft is not properly fitted into the piston . Generally unless you have replaced the slave cylinder recently I would replace that also and then the clutch system is fully serviceable for a long time to come.

I should start by saying a trouble code does not mean a component must be replaced. It only means the signal from the sensor is out of range or the affected circuit needs to be checked out. Code 121 means the signal from the TPS is either out of range or not where the computer thinks it should be. Such as the TPS tells the computer the throttle is closed when it is actually open. You would need to use a scanner to see the data coming from the sensor to tell if it is working or not. The problem could be the throttle or the wiring back to the computer.

It appears that you got it right but to be sure the check is on the timing chain there are 3 black links If you have it right then the black links will line up with the marks. If not then re adjust the gear that is not correct.- ensure that you have the ignition timing right as you may be 180 degrees out

If you have a manual transmission, you may have a problem with with clutch pedal switch. Some GM's have a problem with faulty wiring for this switch behind dash. Only way to check is at fuse panel. Look for power going to switch, and power returning to fuse box. If you need further help, reach me via phone at https://www.6ya.com/expert/david_f2436a37cbb50365
