mitsubishi
eclipse gt
3.0L V6
140,000 miles
I bought an inexpensive scan tool that is throwing the code p0300.
I've replaced the IAC, PCV, throttle body gasket, radiator and changed the oil & filter.
I'm pretty sure the engine was misfiring before I replaced the IAC but it never idled this fast and is very random from 600-1000-1500 then back down again or sometimes not back down at all. the old IAC would stall when stopped and the AC was on. then one day it wouldn't idle at all... tested the ohms and they were near zero on one connector. bought a new one, mikuni brand.
also I think i have air in the brake lines which really makes me notice it at 1500 rpms... last time i did the brakes i didnt bleed the lines, just strong armed the piston back into place and by that i mean used a clamp :)
also i think the guy at the auto store gave me the wrong pcv valve, the picture on the computer was all black, the one that was in the car before was all black but the one they gave me is half white half black.
I have a vacuum gauge being shipped to me that im not sure where to plug in... intake manifold vacuum line? not sure where that is.
also it seems to be leaking oil.. i have checked under the car and it seems to be dropping out close to the alternator and not the plug nor the filter..
also i may have put too much oil in because recently there was some white smoke coming off the belt near the alternator.
threw water on the belt, let it cool... it stopped for a while then happened again but hasn't happened again since that day.
im thinking that the misfire could be plugs, wires, rotor, cap.
first i want to find if there is a vacuum leak though right?
and if i drain some of the oil , she might stop leaking oil? or is that a blown ring?
idle baffles me... could it be the wrong pcv valve? stuck open egr? is that cleanable?
ive got a scan tool, multimeter, haynes manual, internet, some borrowed sockets and soon that vacuum gauge.
and i have my eye on that actron pump/bleeder at sears
any advice would be appreciated.
thanks
mike
