haha. But did you see the part about 3 or so misfires a few months ago?

Jbrew

Perhaps someone shoved a Potata up your tail-pipe ?

Yea, that would be uncomfortable I expect.

a plugging cat can cause that

also it could have contributed to said cat issue

Ford Fan#1

no choice. Have to pay it off before we can sell ( my brother is gong to kill me for using that word ) or get a new one

Ford Fan#1

nah. People know if they get near my truck they might as well be dealing drugs inside a police station..

Jbrew

Yea, that will do it.

A stuck EGR valve can do that as well, - misfires and such, but only at low rpms. With plugged cats, it can't get out of it's own way and that's what happens...just as you described.

Ford Fan#1

would it do it more then a few times? It hasn't missed in months now. And no cel. Wouldn't it be on?

Jbrew

NOPE! No CEL for that. Hell your CARB compliant if your not pushing anything out, - or next to nothin anyway.

There's a few tests you can do. The flow meter at an exhaust shop is one. Another is to install a gauge into one of your intake lines and vac test the engine. The vac readings at certain rpms determines engine health and gives you direction to the problem. It works! You'll need a chart to go by. You can find that on any tech CD or on the net. Some have installed a vac gauge right in the dash lol. Very good at pin-pointing problems once you learn how to read.

Misfires are going to happen here and there regardless. Well, until you totally kill the engine anyway. Running an engine this way is VERY hard on it.

my wallet hates the sound of all of this... Where can I get the exhaust flow thingy done at? I'm in a small town so the shops want to screw you. Or will do it but not do it right. Or are in bread hicks that don't give 2 s**ts about your stuff. So I'm stumped
