Well I need right away from anyone!
My 2000 P71 shows engine code P0442 & I still unable to find issue. My car has been suffering since the code showed up in May of this year. I now have a very small miss in the motor (acts like bad coil but isn't!),And U can hear the miss thro the back exhaust, it bucks, jerking, etc from 0-45 mph in drive <---- It was only between 30-40 mph, sound like the exhaust is a "throat ish / chocked" sound now, no misfire code from COPs , no P0442 code in the last 6 yrs, & its gotten worse.
On 10/11/2011 around 5:30pm my poor P71 started to have a "Light top tap" coming from the motor & that went away after i drove in around the 15 mile gated community, and let it idle (idled shitty) and just turn it off when I got home, I just dont know what too do or whats going on! I'm not the guy to figure this kinda of stuff out , Im more into the aftermarket stuff guy
. I'm hoping it can be a small fix and some major!
This is my conclusion: 1.) 11 yr old charcoal vapor cainster need to be replaced 2.) EGR valve, EGR valve sensor, EGR solenoid or solenoid, 4.)TPS, 5.) catalytic converter 6.) Throttle body. I has to be something at of all in my conclusion.
Please I need some help, some idea on what it may be, Idea on where I can start?
I am more then Happy answer your questions.
