Catalytic converter glowing red, new parts installed
I have a 2002 Chrysler Town and country
3.8L. It started out running rough even
during driving, has cut off but immediately
cut back on. It has brand new spark plugs
brand new wires and also two brand new
coil packs which have had to be replaced
because for some reason they keep cracking
whatever it is is making my catalytic
converter glowing red and smell like it's
burning on fire even if you just crank it up for
a minute. We have had p0353 p1193 and
P0135 show on the computer which we have
replaced but it's still not running right can
someone please help me?!
Once the parts are repalce or the wiring repaired the computer must be reset and then the drive protocols performed before it will run correctly, if those were done and you still have symptoms then something is still not right, you may have to find a shop that does live data testing if normal methods prove that they don't work. HTH
It's been in the shop twice, it will run good for too days then back rough
Could it be a harness?
Could be a wiring issue, but if they were doing live scanning they would see that, you may need a different shop.
A bad O2 sensor could make the engine run rich.
