Help. Xj losing power.
So I have had the jeep a Lil over 2 months now. 1997 cherokee. Has been running great since I've got it. But recently has been giving me some trouble. Has codes p1391 and p0320. Driving down the road and the jeep randomly starts to lose power, when I push the throttle it spits and spudders and backfires. Does it for a Lil bit and than clears up and doesn't do it again. Has a very slight miss at idle but nothing major. Replaced cap, rotor, and plugs so far. Leaning towards the crankshaft position sensor but not sure and wanna spend the least amount of money to fix it as possible.

Also, here's a great thread to start from next time you need to look up what a code means.

If you have a multimeter do a simple continuity test before replacing the sensor. Could be an open line/bad connection and you could save yourself the money for a new sensor.

So I have replaced the crankshaft position sensor, throttle position sensor, cleaned the throttle bottle and iac, checked for vacuum leaks and still got problems. Disconnected the battery while replacing the cps and codes cleared. Still having a rough idle and now the problem seems to be different. The idle is rough and fluctuating and runs like **** only when leaving from a stop. Spits and spudders and than clears up after the rpms are up a little.

Injector plugs clean/getting good connection? I had a similar issue with mine. Crappy idle after I replaced cap, rotor, plugs and wires. #3 Injector plug was corroded and wasnt getting good connection.
Start the jeep and let it idle. Unplug one injector plug at a time, see if the idle changes. If you unplug one and the idle doesnt change then you found the culprit.
