i just swapped my engine in, its a 7mgte. ran 600 miles really good, held boost nice. then this morning at 602 miles it started missfiring in all rpm's. morning time was a plop plop here and there then during lunch time, after warm up. plop! PLOP PLOP like crazy. its not knocking, no loud sounds, no metal sounds or bangs just plopping from the exhaust. then on the way back home form work around night time as it gets colder, rides a little smoother.. btw i have a small trickle of coolant leaking from hose going to firewall and small amounts of power steering fluid comming from... resevoir? help me out guys! this is scary ! what could it be? missfires in all rpms

Have you had a look at your oil and your coolant yet? Start there. Any oil where it shouldn't be? (in radiator) or coolant where it shouldn't be? (in crankcase).
After that, I'd have a look at all my connections electrical, vacuum and exhaust.
Good luck and post with what you find.

yea everything is fine, new sparks, no oil in coolant lol, there shouldnt be any coolant in head. it was real hot that day, you think that might be the cause of it? or is it my pre gapped NGK V's and 1.2mm head gasket combo? i dunno

thanks,
