89 D150 starts and idles great give it gas and falls on face
 
I have a 89 dodge d150. It will start and idle fine but if you try to give it gas it will bawg down and even die. 318 with headers, smog pump removed, new tps, plugs, wires, cap, rotor button, fuel filter. Wot will not take fuel and will backfire through the tbi. Please help love the truck but tired of this issue and contemplating switching to carb.

I don't have a gauge to check it properly. A lot of my tools were recently stolen.

Malfunctioned Coolant Temp Sensor will retard the timing on those.... :)
