Exhaust and Headers?

It is exceptionally possible a wire be left sour or not on tight enough.
Also you might enjoy a vacuum line departed off sucking nouns and giving you the rich mixture you mentioned about on your plugs
you also might hold crossed wires, check the firing order 1342. Vfarina808

Answers: 1st rotten, without proper diagnostics you cannot carry a proper repair... with that mortal said...

2nd, when you replaced the plugs did you replace them 1 at a time or pull them adjectives out then replace them?

3rd, it sounds resembling you have the plug wires on the wrong plugs, find your firing writ and put the plug wires in that charge and your car should run a short time ago fine.

Good luck and hope this helps.
