Ok, some info first. 2008 dodge grand caravan. Two weeks ago I change the plugs and used sea foam to clean the intake. Later that day, it started running extremely bad and had warning lights on dash. I was getting code for mass air flow sensor. Changed mass air flow sensor. Then the o2 sensors would stop working after about 10 min of idle. Changed both o2 sensors. Restart and everything was fine for about 10 min, then rough idle and warning lights. Changed plug wires. Same thing. Got code p0113 and p0123. Throttle position sensor reads at 100%(5 volts) even without car running. Car has been running fine for 2 weeks, but still have warning lights and tps stays at 100%. Used multi meter and checked tps wire harness without it plugged to tps. 2 wires read 5 volts. Checked wire connections on gas peddle, is fine. Running out of ideas.
have the same problem?
