Engine Mechanical problem
1989 Buick Reatta 6 cyl Front Wheel Drive Automatic 148, 00 miles
I just replaced my rear spark plugs on my Reatta. I did the front ones a little while ago and it was no problem. Now that I did the back ones, im afraid that I messed up the firing order and I dont know the cylinder numbers. I know the order is 165432 but I just dont know the cylinder it corresponds to.
