Re: need help bad
Well the check engine light comes on when you have a problem with your o2 sensors. Mine come on and off constantly. Then low oil light would be a faulty sensor cause you say it was just changed. the low rpm movement would be caused by either the air temp sensor(located on the intake) or the maf sensor. also could be something blocking the air path from under.(mine is a 97' and i get leaves and all kinds of crap stuck under there to) also make sure you are using 10w-30 if thats what your engine calls for, i used 20w once to thinken it up and i felt the same thing you are saying, bad shaking. but start with the cheap stuff first. new maf's could cost a pretty penny and so do 02 sensors if you gotta do both. good luckHigh hopes for a quick 6

Re: need help bad
for the oil, there could be an oil level sensor that is bad, or the oil sending unit could be going out. however, do not rule out that you do not have a bad leak (loose drain plug, loose oil filter), oil pump that is starting to go out, or blocked oil passage somewhere.. probably is a sensor, but if one of those three things is occuring, then you will ruin your motor before you discover it. just be careful.
the idle could be a few things.. if you have a 3.8l, have the codes scanned at someplace like autozone or advanced... they'll do it for free and should be able tohelp pin point the problem...Phill<br /><br />95 camaro... need money for turbo project... <br />94 S10 Blazer - winter beater - infinity system to be installed soon<br /><br />\"The man who says it cant be done should not interrupt the man doing it...\"
