okay my truck decided to start acting like a little b1tch last night.
drove around doing some errands, parked it for about 2 hours, started it back up and the Service Engine Soon light was flashing, running like sh1t, and backfiring. Parked, looked at the manual and it said that if the SES light is flashing, it's probably an miss or an emissions problem, ease off the gas, drive it to a dealer etc, so I looked under the hood and made sure all the plugs were in, wires connected and tight, etc. Started back up, drove to Advance (found out they don't have a code reader, but I got some fuses for my other non-functional vehicle), drove home and parked it. Running like chit the whole time, mostly below 1500-2000 rpms, seems to run fine above that.
It's been about 50k since my last tuneup, so I'm thinking I'll pull the codes, then do plugs, wires, cap/rotor and see if it fixes anything. Since it runs fine at higher RPMs I'm worried it may be an ignition module problem...like the electronic advance isn't working right, but I'm hoping it's just a plug or a wire.
Any ideas?
Jerry you gonna be around tonight?
