I'm not sure if you can on that model. If it has a distributor, you can loosen the hold down bolt and turn it to advance or retard your timing. If it doesn't have a distributor, it set by the ecm.

The 3.3L has a timing chain.
10 deg BTDC
It doesn't have one. It uses a timing chain that does not need replacing
broken timing belt
try adjusting the ignition timing(or getting a mechanic to do it)
IF you have already set the timing to spec, you alter timing by loosening the distributor and turning the base to adjust timing. You will need a timing light to measure the timing. Pull out the spout before adjusting so the computer will not alter the timing. HTH.
this is the correct procedure http://www.kick-fix.com/IGN_timing/8v-procedure.html
60 to 100k depending on service
To change the timing belt on a 1991 Dodge Spirit, first disconnect the battery and remove the engine covers to access the timing belt. Align the timing marks on the crankshaft and camshaft, then remove the old belt by loosening the tensioner and taking off the belt. Install the new timing belt, ensuring it’s properly aligned with the timing marks, and reassemble by tightening the tensioner. Finally, reattach the engine covers and reconnect the battery before starting the engine to check for proper operation.
It would cost about 260 dollars.
A Timing Belt, A Serpitine Belt, A Power Steering Belt, and if you have A/C A Belt for that too...
