View Full Version : Hesitation between 60 & 70 mph

07-11-2007, 01:03 PM
We are in process of selling my boss's 2001 Grand Am SE for him. One of the potential buyers reported a hesitation/lag in acceleration when reaching between 60 & 70 mph. I'm going to check for a clogged catalytic convertor and fuel filter when I get home. I am posting because I want to know what else I should check if neither of these is the case. My boss recently replaced the TPS, so that is not the cause either.

Thanks in advance for any suggestions.

Check the plugs and wires.

hate to revive a dead thread but did you ever find the culprit?
