Things seem to keep going in different directions here with very little info being available to diagnose from.

If you took one picture looking in from the passenger front corner.. we'd be able to see the front exhaust, pulley and other things to tell what's on this engine.

If you found/listed that info from the paperwork we'd be able to tell what's on this car

If you told us how long the plugs etc and even fuel have been in the car, that would tell us a lot

What I'm saying is.. some of us would really like to help out and there's only one hang up.
