got a 1988 f250 with the 302 5.0 small block and my problem starts when I first start it, it starts up will die out if I don't give it has right after then jumps up to about 1200 rpms and will sit there if I let it if I tap the gas it goes down and sits at 900 but if I hit the gas hard it sputters and doesn't jump on it like it should and when I drive it it'll bog down off the clutch in 1st and 2nd gear and after that it will be fine but if I drive around for say 30 min if I come to a stop and try to go again it'll big down and shut off and won't start until being let sit for about 10 to 15 min I have replaced my Ecu due to water damage cleared up for a day or 2 I've replaced my fuel pump, fuel filters, o2 sensor, throttle position sensor, map sensor, and have new plugs new wires and new distributor cap

 

Lots of parts.....what about checking for codes?

Fuel pressure been checked?

 

Fuel pressure was good and I haven't been able to run any codes because I don't have access to those kind of tools and she won't make it far enough down the road to get someone else to run codes

 

Just ran codes on it and I got a code22 witch says is map sensor which was just replaced and a code 122 which is my tps which was also just replaced could I have a vacuum leak?

 

I see you started another thread...

 

Are you sure Code 22 is really System Pass (Code 11 then repeated).

Code 122 is probably the separator flash (1) then Code 11 again.

 

Okay so what would my problem be?

 

Define "Fuel pressure was good" in Post# 3

If the pressure really is good then you probably have a vacuum leak.

When the truck does not start back up (won't start until being let sit for about 10 to 15 min) check to see if you are missing spark or fuel pressure.

 

I'd suggest cleaning your Idle Air Control (IAC) valve. Search the forums for that process. It's fairly simple. If that solves the problem for a while then it gets bad again, replace it.

 

And don't rule out some vacuum problems. Try the spray test.
