Question about 2002 Ford Ranger Regular Cab
The check engine light in my 2002 Ford Ranger is on. The truck is running perfectly and only has 19,300 miles, but a diagnostic test performed at Autozone found that cylinder 1 is misfiring. There is no indication of a misfire, but I took Autozone's advice and changed the spark plug (which was in great condition), checked the wire (which was recieving a good spark) and disconnected the battery for 5 minutes to reset the code, but the check engine light came back on a few days later.
Ignition Coil Pack
Clog or dirty fuel injector
Evap canister purge valve
you have 3 type of engine for your truck

The reason why the service light come on because it is a hard code
not a soft code.

Tips for a great answer:
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
Also have the charging system tested as a low system voltage can cause this same symptom.

SERVICE PROCEDURE FOR VEHICLES WITH RUNS ROUGH/MISFIRE CONDITION:
1. Perform relative compression check on all cylinders. If abnormal, check cylinder leakage and actual compression for "low" cylinders refer to Workshop Manual (WSM), Section 303-00.
2. If leakage/compression check indicates a valve train concern, per valve train diagnostics in WSM, Section 303-00, replace cylinder head and cam assembly, pipe plugs and timing chain tensioner, per procedure outlined in WSM, Section 303-01.
3. If cylinder leakage and compression tests are inconclusive, perform misfire diagnostic, per TSB 05-22-8.
