I have a 302 single bore throttle body in a 90 ford f250 does any body no the factory settingsfor the tps?

 

Anywhere between 0.6-1.0 VDC at closed throttle.

 

Is that key on engine off?

 

Correct

 

One more question what do I set the voltmeter on?

 

DC Volts

For reference: Fuel Injection Technical Library » Digital Volt Meters

 

OK cool thank u I guess there is no setting to make my MPG any better? I no the 250 r heavy but dam lol just rebuilt the motor 302 ho. Any advise?

 

There is no TPS setting to gain MPGs. It's either in range or not. The computer is always looking for the lowest closed throttle voltage then adjusts itself accordingly.

So you have a F250 with a 5.0L engine. Poor choice for Ford to make or anyone to purchase. Since you stated before you had a single bore throttle body I assume you swapped in an intake or complete engine from a Mustang? Regardless the TPS setting is the same.

 

Yeah its from a mustang non mass air, cold air intake, Msd 6al, headers it runs great but MPG suck bad

 

Define "suck bad", what MPGs are you getting and under what driving conditions? Have you checked for codes. Did you retain any of the EGR or smog equipment? The more stuff you pull off then try to trick the computer the more likely you are to effectively decrease the MPGs and performance.

 

Have egr no emissions tho
