Hello thanks for your time I have 06 armada se with 178000 on it now I have never had any problems before my gas light came on so I added gas from a station I never used before and after this all the problems started. I couldn't drive it over 50 loss of power hear a pinging and rattling noise want go in overdrive, alot of smoke coming from I think the manifold or the catalytic converter I can hear an exhaust leak but there is no check engine light on never has been does anyone know what is going on with my armada thanks for your time jerry
It could be a plug/coil issue.... I would also suggest possibly adding a bottle of techron fuel system cleaner and avoiding that station in the future!
P0300 tried heet red in gas and put 93 octane in . Now it want run over 20 mph . It sounds like a hiss coming from manifold or cat one guy said it blowed a seal in the manifold. Alot of smoke comes from manifold or cat when I turn it off. Thanks for your Time and answers
Runs real rough no power at all about 20 mph is all it will go real high rpms car cranks fine every time just want go anywhere and still sounds like it tries to backfire through the air filter or intake I'm not sure
