- 97 Sport Trac
Ok here what i've got,a 97 explorer sport trac, with the 4.0l SOHC, starts everytime first crank, idle starts out at about 1200, and drops to 500 and stalls out. If i give it gas and help it idle it will stay running, the more gas i give it the rougher it is till i hold an idle than after a few seconds it smooth out, and then go right back to running rough. If i take my foot off the gas it stalls out. Heres what ive replaced, the IAC sensor, the TPS sensor, the upper and lower intake manifold o-rings, the spark plugs and wires, the starter relay and the starter (seperate problem but im listing everything...), all the timing chains and tensioners, the oil pump, the water pump, thermostat, i'm at my wits end. Alot of this stuff was replaced because i had a bad chain and had to pull the engine out to get to it. I've checked it for computer codes, but its not throwing any. If anybody has any ideas please let me know, i cant figure it out and its driving me mad
