RUNNING ROUGH

1998 Acura RL

Engine Performance problem
1998 Acura RL 6 cyl Front Wheel Drive Automatic 138000 miles

1998 Acura RL check engine light comes on. Diagnostics indicate that it could be EGR valve, or fuel injectors, or a faulty 2nd cylinder. All 6 cylinders are firing normally. It's not the coils either.\R\n
I dumped a can of injector cleaner in it and ran it almost completely out of gas. Then refilled with high-test. I also changed oil and refilled with 4 quarts oil, 1 quart Marvel Mystery Oil. It's still running rough. It idles rough, and runs rough until about 20 mph, then it smooths out.

Suggestions?

Replace your EGR VALVE.
