Any help would be greatly appreciated. Thanks, Billy

Hi Bill, I just wanted to add my thoughts on the issue. I am not an expert but I own a Mazda GLC. On the electrical side, you might try to check the vacuum advance unit for proper operation. With the engine idling connect a vacuum guage to the advance unit and apply vacuum. The timing should be advanced according to the vacuum applied. Replace unit if faulty.
Note, faulty unit will also cause overheating on the freeway.
I have a check for the CAT as well, loosen the exhaust manifold bolts and try the acceleration again. Improvement means the CAT is plugged.
Note the CAT problem was caused by another problem (excess fuel usage?)
Excess fuel damages the CAT.
Later DAZE...
