87 F150 302, starts fine, revs to 1200 then dies, will do this 3-4 times then stay running, only code I have is 87, scratchy TPS, any way to clean it?

 

I'd replace it. A new Motorcraft is $52.79 at Rockauto.com.

 

code 87 isnt a tps code
87- Fuel pump primary circuit fault

will the truck stay running if you hold the throttle open a little bit? have you checked the fuel pressure at start up? check the connections to the pump and relay, make sure there arent any loose wires too.

 

If it's a fuel pressure problem, I'd probably change the fuel filter on general principle.

 

bad mem, it was 33. I replaced both fuel pumps is where the 87 came from

 

still not a tps code
33- egr valve opening not detected.
do a suck test/ or hook a little vacuum pump to make sure the egr is opening, if it doesnt open then replace the egr, if it does open then make sure the sensor changes resistance as the egr opens and closes.
