i have a 99 atx with about 120xxx miles. i have one code for the cam shaft possition sensor. When the car is cold(first 5min-10min in winter). i first start driving and when i let off the throttle, by either letting off or putting it into neutral(i put it in neutral as i have 2 bad motor mounts and hate the shaking when stoped). the rpms drop and the engine bogs down and 1-4 times a day it will stall. It also bogs down but doesnt die if i rev in neutral(in park or neutral, stopped). once it is warm it goes away. The bogging down never goes away but gets better. the engine stops stalling once it warms up.
another thing, is that sometimes(about half of the time). after accelerating hard then fully letting off the gas. the rpms will start to drop then hang at about 2,000. Also, i have a large amount of carbon build up in my exhuast pipes(looked at my dads s-10 and tarues, which compared to me have less then half as much). any ideas about this stuff?
the maintinance i have done to the car in the past 8months is:
new fuel filter, a few bottles of injector cleaner and such. seafoam in the crankcase(then oil change) and seafoam threw the intake, new spark plugs(bouch +2), new alternator, new serp belt. new battery, cooling system flush, i just changed to valvoline synth blend high millage motor oil(but the problem was around befor this)... thats all i can remember right now
(i have installed a tach, that is how i know my rpms)
