I have a 92 Ford-F-150 that we have been having a little trouble with.It seems like when you are going up a hill sometimes it does not have any power.You can push the pedal to the floor and it just kinda starts jumping like it is missing and then the check engine light will come on for a little bit and then go back off. Just had this motor put in and has all new plugs, wires and everything. Put Code reader on it and the codes are: 121-closed throttle voltage higher or lower than exspected. 332-Insufficient EGR flow detected. 334-EGR closed valve voltage high. 327-EVP/EPT circuit below minimum voltage. Thought maybe that i needed a new EGR VALVE. Does anyone know if that is what i would need? Thanks!
You may need an EGR valve, or have problems with it's sensor or controller,.............but I don't think the problems you are having going up a hill are EGR related.
332-Insufficient EGR flow detected. 334-EGR closed valve voltage high. 327-EVP/EPT circuit below minimum voltage
Those are probably falseif the engine's off...without the engine running the code readerdoesn't know any better.....does your exhaust smell horrible when it does run?
Hmmm that's weird...usually code readers allow you to run with either KOEO (engine off) or KOER (engine running)...you might want to have your cat checked out nontheless...also test the egr yourself.....I forget how to engage the diaphram within but I'm sure someone knows.....
