build time

[Mustangstacey]

i had the same problem, i changed my spark plugs....checked the oil...nothing on signs of nothing...turns out injector cleaner took care of the problem

[nightfire1800]

only thing crappy about it is. Bad year 94-95 or atleast im pretty sure since they had lots of problems. Anyhow dont downtalk the v6, the only thing wrong with it would be your crappy euro tail lights :-/

[Bellmyer033]

no, its the crappy v6

[Eridanio15]

is it the gt

[kohldstayr]

is there oil in it? What's the oil pressure? Since it locked up, it's probably some spun bearings man. Just my opinion though

[Bellmyer033]

yea, there was oil, and perfect oil pressure but, i found the problem, it was a broken berring on cylinder 3, it shot through the block, but, i got a new engine, it's all good now :-)
