Flasher/Blinker Problems

I have had an annoying problem for a while and can't seem to find a solution. I recently heard of 12volt so I figured I'll give it a try... I drive a '95 Honda Civic (EX). My blinkers blink very fast, like they would when a bulb has burned out. It started when I received some wrong info about bulb sizes and put two 1156 (single filament) bulbs in the front lights where 1157 (dual filament)bulbs should go. Weird things happened, so I checked it out and realized my mistake. I have since replaced all 4 blinking bulbs, tried a new flasher relay, but cannot stop the hyper blinking! The hazard switch still operates the lights at normal speed and seems unaffected. I was hoping someone here may have some ideas on how to fix this. How is the wiring different between the blinkers and hazards where one might work and not the other? Are there any other obvious places I should look? I know the hyper blinkers people have work because of a different resistor in the relay. I was thinking of maybe soldering a new resistor in to create this effect, just opposite (slowing them down). But I would really like the find the actual problem, not just cover it up. Anyone know what putting the wrong size bulbs in would do to cause a problem? Thanks for reading and for any help... --Joe
