So I got a new (to me) '95 I6 auto F150. She drives great, but there are a few issues.

1; Once warm, it has problems starting. At first it seems like a bad battery (it gets to a point were it wont even turn over, then I would need a jump). But once it does start, it will run for about 1-2 seconds, then die, unless I give it gas for a few seconds. It seems to start better from a cold start.

2; Maybe related to the starting issues, it has a mild miss at idle and part throttle that comes and goes.

3; Maybe not a problem, but the oil temp will reach about 3/4 the way once warm.

4; The coolant temp never reaches more then 1/8, even when in traffic, I'm guessing thermostat stuck open

5; The turn signals blink pretty slow, again, might be normal for this truck, dunno.

6; The steering wheel has a good bit of play in it. Again, my guess is tie-rods.

7; And lastly, the gas pedal has to be pushed down a good bit before it will actually go. Would a simple throttle cable adjustment solve this?


A few mods I plan on doing;

Electric radiator fans
"Warm air" intake to improve gas mileage
Front air dam, again for fuel mileage
Cover all the rusted areas (i.e. the whole frame and suspension components) in POR-15

Any help would be greatly appreciated!

 

1. i would first make sure the battery is the correct one. my truck came with the wrong battery once and when i was putting the truck to use the truck lost all power and died, when i opened the hood the battery was swelled out and you could hear it boiling.
2. you need to get some goot throttle body cleaner and clean it and the air idle control valve.
3. these trucks dont have oil temps. that is the oil pressure gauge. anad thats a good reading.
4. either the termostat is stuck or not in at all. i would flush the cooling system and replace the thermo stat. use a 192 deg one I6's run better with the stock 192 deg stat.
5. as long as they blink i wouldnt worry about it.
6. tie rods ball joints or a worn steering box could all cause this.
7. i would find some cable lube and use that on the cable first( comes in a pen like container). and see if that helps any.

your mods>>>
---elec fans is a good one, you can use junk yard parts to save some cash. look for mark iv's or mid 90's t-birds. for the fans.
---anything to let motor breath better is good, but with the I6 you already have what could be consitered a ram air. just put in a good air filter like a K&N and you'll be good to go.
---a front air dam wont help much if any at all. these trucks are shaped like bricks.
---anything to stop and cover the rust is good.

 

Fixed the battery issue, it was a loose ground. Also replaced the thermostat.

The truck has been getting harder and harder to start. Finally it wouldn't start at all, just turned over and sputtered. Got some carb cleaner and sprayed it in the throttle body, it started right up, but will still miss and sputter up until about 30-40mph when it smooths out. It doesn't seem to be spark related, so I'm thinking fuel pump or clogged injectors.

That being said, I found out my cruise control still works, lol.

 

I noticed that when I unplug the IAC, the truck will start fine, (but still have a miss under load/when accelerating.

I'm leaning toward a new IAC, but I don't see how that could cause the miss when accelerating.

 

Well I ran the codes, but unfortunately I can't make heads or tails of them (the directions to read them are a bit confusing).

Here are the codes,
