I have a 1998 ranger xlt 4.0l 5 speed 4wd truck with cranked torsion bars and 33s and it has three problems. This is going to be an essay but most of these threads are just asking questions the publisher should put out there to begin with. Check engine light reads lean banks. Shit gas mileage like 13mpg highway (bigger tires/lift make it that bad). What I have done/What is new:
new exhaust from headers back, new plugs, coil pack, IAC valve, egr valve, cleaned throttle body, MAF sensor, air filter (aftermarket K&n), new battery, new TPS sensor, all vacuum lines have been looked over and replaced if needed (that I can see), more and more I'll probably think of
1. Weak start up: on cold starts especially it cranks right at the key turn, sputters at less than 500 rpm, surges on its own to over 1500 rpm for about 30 seconds, falls down to 1000, then after driving for a while and stopping at red lights and such, I can see it idles at around 750. During start up it shakes, tries to die, has no throttle response until shes ready to go meaning after the surge and at 1k rpm idle. My truck runs the show here and I want to be in control. Some days she wont even start or itll take several cranks and fluttering the gas to get her going. Also going uphill is a struggle, thinking problem is related. Decelerates from 70mph to around 55mph over a bridge I take (big tires?). Lean mixture is problem...but where I've sprayed the engine bay with cleaner while running trying to get rpms down and find vacuum leak but no luck.
2. Hot air blows out of foot vents all the time, all air is always hot from AC vents: Part of the gas mileage problem could be I always have windows down even at 60+mph.. beside the point. This hot air blows through foot vents when the AC is off and it cooks the whole truck, radio buttons become hot, things in glove box, ect. The Ac will change intensity settings and all the directional air paths work when switched. It is just always blazing hot and blows from foot vents after driving for about 15 minutes. I live in FL... going to need new seats after this fix as these have been soaking up sweat for a while now... I've gotten down a looked behind the dash but never taken it off, changing the direction of air settings will move the vacuum pumps under the dash that i can see and direct air. I had hoped a vacuum leak would solve AC and start up problem... life ain't that easy.
3. GEM relay bad? Wiper blades, dome light, 4wd, power windows don't work all at same time, when dome light works they all work, it flicks on here and there. Could all this heat behind the dash be frying my electrics?
Any help at any of these problems, please. Been driving my dad and I crazy for months.
