Running rough after plugged cat replaced
My catalytic converter plugged up and truck stalled but I had to drive it half a mile or so to get to work off a busy street. I was thinking this can't be good for the engine.
Figured out what it was, drilled a 1" hole in the cat pipe ahead of cat and was able to drive it home. Now running with a stutter at same rpm when shifting gears.
Got cat replaced thanks Rockauto. Timing belt had jumped maybe 2 teeth, got mixed up with the timing marks. Reinstalled correctly eventually with info from here. Replaced twice before after breakage.
Runs with stutter especially in 5th, doesn't like 5th gear. reduced power.
#2 Sparkplug wire was arcing to block. Replaced exhaust side wires and plugs Motorcraft. plugs ok , wires pretty overdue
Codes
P0401 EGR
P0102 IAC Cycling too much
P0351 , 352 ignition coils
P1443 evap emission
P0 ??? MAF low output
Cleaned egr some improvement, tried blanking it off no improvement
Cleaned IAC seems ok idles faster when elect connector plugged in
Cleaned throttle body, inside was black
Cleaned MAF looked clean before cleaning. Haven't unplugged it and tried driving yet
Evap code not supposed to affect seriously
Is it possible I smoked the MAF badly driving with it plugged bad enough that it wouldn't stay running at idle ?
----------
Forgot to say unplugged exhaust side coil, still runs the same.
Looked in the dark no arcing.
Floored won't go over 50 in 4th
Haven't checked fuel
Something happened with cat plugged and trying to drive so trying to focus on that and related stuff
