Subject: Backfiring when accelerating
IP: Logged

Message:
I just wanted to run this by people before I take my truck to the shop. My ’93 Dakota (V6, manual transmission) is backfiring when I try to accelerate. It is fine when I just sit and rev the engine, but if I have the transmission engaged and try to accelerate more that at just a crawl, it starts to sputter and backfire. Once I it get up to speed, it is fine and does not backfire. I did the key trick and go the codes of 12, 32, 55. The various sources for error codes on the board here seem to point to the Erg valve or a vacuum pressure problem I think.

As a little history on this problem, it only started happening recently during some colder weather here in Iowa. I first thought it may have been a “bad gas” issue (moisture, etc) so I ran thought that tank of gas and have refilled the tank a couple times now with a “known good” gas and with different octanes of gas (2 tanks at 89 octane and 2 tanks at 87 octane) and I am still having the same issue. That is when I checked the codes and started doing research on this board. As a side note, I know I need a new exhaust system soon (it is long overdue in fact, I have just not gotten around to it).

Any thoughts or things I can check in my driveway? Fixing it myself is always cheaper that taking it into the shop to have it looked at.

I had the same problem with my 97...It was terible. I swapped out a few parts, but I believe the main reason for it backfiring was the wire, not the plug, the wire that plugged into the coil was coming loose.

My truck would backfire, choke and die, I would have to pull over and wiggle the wire to the coil, tape it to hell so it could stay in place, and it would work fine.

John, what year, how many miles, any mods & when was last service? There's a list starting with Distributor pick-up, timing, cracked cap, burned rotor button, burned contacts, crank sensor dirty, bad plug wires, crud on valves, burnt valves, list goes on & on.
Check 1st for a cracked distributor cap, will look like a pencil lead drawing, usually on inside from 1 contact to another.

Good Luck,
Shank
