Looks like Seafoam fixed my hesitation problem. No hesitation in 1.5 weeks. Thanks to everyone that made suggestions and especially to Menappi for his Seafoam suggestion. He saved me a ton of money and aggravation. Thanks. Have you had any hesitation since??? Lexus diagnosed mine with clogged catalytic converters; howver, that didn't fix the problem. So they replaced the wires and the coil packs. This solved the problem. So if you still have the problem this might be a place to look. The symptoms you described were identical to mine, but they are gone now. FINALLY! Hello, I too have been feeling this hesitation in my '02 GS430. I cleaned out my MAF the other day using CRC Mass Air Flow Sensor Cleaner but it didn't help. I'm going to try the Seafoam suggestion to see if that works and if not, I too will probably purchase wires and coil packs. Can you clarify that the wires I need to replace are the spark plug wires and the coil packs (ignition coil?) are what the spark plug wires are attached to? If that does not work, I'll look into replacing the MAF sensor. Where can I buy the wires and coils and MAF sensor for cheap? Thanks again everyone!
