back firing.
96 ranger xlt 5spd manual.
about 2-3months ago, all my spark plugs went bad, causing my cat to go bad, got the plugs and wires replaced, and new cat.
about 2 weeks ago it began to back fire, not bad, just small ones when i reved it between 2-3k rpms. why would it do this, bad plugs again? someone shed some light my way please.
thanks.

Hi aaronsxs;
Welcome to the FTE Family! Off the top of my head i'd say to check the timing by distributor or for EFI's the TP sensor which assists in regulating the timing! Your IAC valve may also need cleaning!COME - BACK!

My '92 was backfiring when I revved between 2-3K as well, but mine was backfiring through the intake. Is that what yours is doing too?
After I spent a crapload of time on it, I later found a large crack in my catalytic converter. Since my computer wasn't giving or storing codes, I researched about cracked cats and found out it can be caused by a malfunctioning O2 sensor. I changed it and the truck ran like new....no backfires...more power....huge gas mileage increases too. All that for $40.99!

about 2-3 months ago i had the spark plugs and wires removed, i was going to go back to the same place and have them check the distributor, i put some fuel injecotr cleaner in yesterday, thought maybe it was dirty, its a long shot, but if that doesnt do it ill take it in.
yeah, the timing may be a problem, your the 3rd person to tell me something about the timing, so in any case ill have to take it in, that would be a little out of my expertize. i mainly deal with fabricating interior custom jobs, but i know enough under the hood to know when somethings not right.
thanks all.
