90 Buick w/ 184,000 mi. I recently went through a flooded intersection realized the water was too high and backed back out. After that I noticed the cars shakes and shudders violently upon acceleration. If I let off the gas it runs fine, it only shakes on acceleration. Any suggestions?
Ok I've talked with several " car guys" and it seems that it may be the catalytic converter. I know the converter can fouled up from excessive temperature but can it also get damaged from water? That is the only thing I can think of.
