97' ranger won't idle cold (sometimes) ?
I purchased a 97 ranger 2wd XLT standard cab 5 speed manual last January for $1100.
truck has some dents but no rust with 128,000 miles on it. previous owner had many new parts installed. new exhaust from headers back, o2 sensors (bad news bosh sensors), MAF sensor, Fuel pump and sending unit, and IAC. since i bought it i replaced quite a bit, New leaf spring hangers and bushings, coolant temp sensor (more bad news all they had was valucraft), TPS (airtex and wells), Thermostat, U-joints, complete re-gasket of upper engine due to leaking valve cover (valve cover, lower intake, fuel injector O-rings, upper intake, egr, throttle body, and iac gaskets) the entire re-gasket i did because on rock auto a valve cover gasket alone was $10 and a (fel-pro) kit was $17).
Now sometimes i can go out and it starts and runs on it's own fine, other times i go out and it immediately stalls i have to rev the engine for 10-15 sec then i have to hold the idle manually for 1-2 min then it's fine. it runs fine when warm (but has some hesitation in low rpm can floor it it does nothing till about 2000 RPM then launches like it should) but other than that it runs good climbs hills fine no stalling.
From what i've read (I believe on this site) the hesitation is due to fuel pressure so i'm gonna head up to the autozone and rent a fuel pressure gauge, I believe i need to have 30-35 PSI correct me if i'm wrong.
ok I hope i have included enough information to make a accurate diagnosis ohh 1997 Ford Ranger XLT 2.3L 2WD standard cab 108" wheelbase
