Asked by Sep 01, 2011 at 05:55 PM about the Ford E-150

Question type: Maintenance & Repair

1999 E-150 5.4 replaced MAF, fuel filter, had CAT checked, EGR pressure sensor,  IAC and several other things runs alot better but I noticed when I turn on the air conditioner it runs a lot worst.  now what still thinking it must be the EGR valve itself

3 Answers

all the EGR does is work with the Idle,ruel that out.sounds like the fuel injectors may be dirty run a bottle of fuel injection cleaner in a full tank of gas,will clean them up.the gas we have today,with the ethonol in it is not worth a crap.
