Check Engine - Ford F150 Forum

I have a 97 F150 with a check engine light on. I've had the code pulled at Auto Zone, do have it with me though. The said it indicated insufficient flow and was most likely the EGR. I replaced it and the light went off for about 50 miles. I went back and got the same reading again and this time replaced the pressure sensor and again had the same results. What should i check next?

Clean the EGR passages in the intake.

Ok i have read alot about the egr valve and I noticed that you had said that you can remove the egr valve and block it off with a tuner if it is a eec4? but not an eec 5? what is that and where would i look to find it on the truck? The other problem I have is that the egr tube going to my exhaust manifold has completely rusted off and I cannot fix it without taking the manifold off. My truck is a 98 f-150 extended cab off road 4x4 with a 4.6 and 137,000 miles so manifold removal will be no easy task there fore i would like to just block it off. I think it is the problem as I accelerate( to the floor) it hesitates and does not pick up rpm like it should. I have put new plugs and wires on it @ 98,000 miles and I have run several cans of fuel injector cleaner thru it as well as change gas and octane. thanks for any advice
