brown **** as u put it in coolant is most likely oil which would probably mean head gasket, this will not necessarily cause a loss in compression your numbers are ok typically 10% variance or less ok if i remember. as far as reving problem or whaterver my guess is electrically related, map or tps maybe

x2. brown **** screams oil to me.

doesnt make sense to me why the compression in the 4th cylinder is so high. stock compression on that motor is 185 across the board right?

see thats what im saying.....i still dont know whats wrong with the raving...i checked my map and tps....all good....can it be one of my injector?

IACV hooked up? as for brown **** in your coolant, flush your radiator, it doesn't always mean headgasket. If the problem continues perform a leakdown test.

when u say checked like check for cel or check with multimeter or something of that nature, for injector u can use noide light of listen to check each for clicking check fuel pressure describe the revvin problem more you said when revving hi rpm wont go past 3000 dont understand i dont consider 3k high rpm is it free rev or underload.

As for not revving past 3k RPM check your dizzy. Any CEL's?

Goddamn.

1.) it's "revving"

2.) those compression numbers are good

3.) brown **** in your coolant can be any number of things. Since you can't seem to describe it any better than "brown ****" we can't really help you. Is it gel? Is it light brown or dark brown? Is it a liquid? Does it float on top of the coolant? What does it smell like?

4.) do you have any codes?

How do you accrue 4000+ posts on this site without learning how you should post your problems?
