Have been waiting for a Catalytic Converter for our 2005 F-150 truck since Feb. 24th ,2009. Took it to the dealer (under warranty). Have called Ford to complain. Started in March/It is now the end of June. Keep telling me next month/no they say July 22nd. Meantime my fail safe mode has come on. This is the only vehicle i have. Summertime/we camp alot. Can't do anything til i get this fixed.

If it is that big of a deal getting a CAT. Just remove it and put an extension tube in there in its place until the part comes in. The down stream O2 sensor will set a code of poor CAT efficiency, but who cares! Your truck will still run.

93 f150 with 5.0 it is hard starting but idles good if i baby it it will go down the road but if i acclerate normal it acts like it out of fuel if i stay on the acclerator itll stall if i back off of it alittle it regains power .ive replaced fuel filter ,o2 sen.,fuel regulator ,air filter ,roter, dis.cap, and cheched other sensors by unpluging and looking at the check engine light and they all came on when unpluged and went off plug in. it has dual tanks and runs the same on both. help!!!!!!!!!!

Jul 24, 2009 (7:17 am)
I have a 99 F350 V10. I recieved the EGR system fault code. I replaced the EGR Valve and sensor and I still receive the code even after resetting the check engine light. Does anyone know what outhere things would cause this code?

I would check the vacuum line to the EGR to make sure there is no problem with it. Pop

If your trouble code is "EGR malfuction" Here are the possible causes: Electrical, EGR, EVR or DPFE, disconected hose or clogged or broken DPFE tube.
You already replaced the EGR so that wasn't it. If it is an electrical problem, ouch very hard to diagnose.
Other causes and most common are DPFE (Differential Presure Fedback EGR sensor) or EVR (Electronic vaccum Regulator to EGR) I know a real mouth full.
1st: If you are not experiencing weird idle changes along with this trouble code, it is unlikely that the EVR is malfuctioning. It could be not working at all and not opening the EGR with vaccum. This is the cheaper sensor too. About $35
2nd: On your exhuast manifold are 2 tubes one bigger than the other leading up to the DPFE. This sensor reads back pressure changes in the exhuast when the EGR is told to open. If the signal is not correct, bingo....t-code. Check to see if the tubes are clogged up or if one of the hoses came off the DPFE sensor. This sensor isnt cheap! If you have an exhuast leak, fix it. Insufficient back pressure in the exhuast can throw this sensor off also.
You seem like a smart guy. After each test repair reset PCM and test drive. Keep track of what you have eliminated as the cause such as the EGR. This may take some time to figure out. I do this for a living and this t-code can be a bastard sometimes. One way of testing the EVR is to temporarely install a vaccum guage inline with a vaccum tee to your EGR and put the guage so you can see it. Drive and look for vaccum being applied and changing by the system while your driving around..
Get back to me if you want me detail how to test the DPFE. I have the right equipment, but it can be tested other ways, its just hard that way. Good luck.
#156 of 252 engine problem

A few days ago my engine light came on and the engine started missing. Today the engine started missing worse and the light started flashing. After I stopped the engine and restarted it the light was off and it didnt miss anymore. Any ideas what's going on?
#157 of 252 '87 F250 RUNNING BAD
Aug 29, 2009 (1:06 am)
Have an 1987 F250 4x4, 302V8,4sp. trans., reg. cab. The thing runs fine for the
first 1/2hr. or hr. of the day, then it starts running really rough in the low RPM's.
I have to about floor it to take off in 1st gear when I used to take off in 2nd gear.
The RPM's also fluctuate when idilng and sometimes it will just die driving down
the road at which this point I switch to the other tank and that keeps me going
but still runs the same. Checked the timing the plugs, and looked for any bad
vaccuum lines but can't seem to make things any better. Would appreciate any
advice from anyone. Thanks.

sounds like you could be having some vapor lock problems.
