Serious Problem Any Ideas?

I recently had someone do a jdm h22 swap into my prelude. It ran great for about 3 months. Randomly it started to short out really bad when it rained, many things as far as lights on and off, tack dropping up and down and last it melted the plastic around my throttle cable and snapped the cable. I just pulled the car out yesterday and with no rain it was doing this same thing again. I really have no idea what this could be. If anyone has any suggestions that would be greatly appreciated! thanks,

Yeah we did I put a chipped p28 in. When it was dry and no rain or anything it runs great. the only electrical done was the p28 and vtech selanoid. I looked over the wiring millions of times.

Re: Serious Problem Any Ideas?

are there any leaks/puddles inside the car? particularly near the ECU?

when i had a slight water leak, i was inside the car while my pops ran a running hose over the exterior of the car, and we isolated where it was coming from like that.

Re: Serious Problem Any Ideas?

generally when **** like this starts to happen its because of a loose or spliced connection.. trace back the wiring to see if there are any cuts in the loom..when i did a tranny swap the mechanic trapped the ac loom under the rad which caused damage to the wiring and melted it. usually its because the mechanic has ****ed up somewhere

Re: Serious Problem Any Ideas?

Yo certainly don't have a minimal issue like a bad sensor or part. You have a serious short on more than one level. Your tach issue could be sourced from the distributor, little corosion, may not be serious and woul dbe explained by water. Change in resistance alters tach signal or something of the sort. Also, try what neck said. Pull up your carpet and check out the ecu. Look for water under there as well. With your headlights, check the underhood fuse panel. The fuses and relays for the headlights are inthere. Try and remove the cover from it and look for signs or water/corrosion or damage. Mice and squirrels commonly inhabit engine compartments. You could have chewed wires and a peice of sheet metal shorting your system. Now as for your throttle cable. This is a bad deal! The fact that you had enough current to burn the cables sheilding and not blow a fuse is scary. Youre lucky you still have your car. Try and find a wire near your throttle. What my guess is, is that you turned your thottle into a path to ground. Do you have an amplifier or wiring in your car? Commonly we see unfused wires running to amps and if they are unfused the installer was probably amature enough to run the wire through the steering column boot orrrr....throttle boot!!! Check out those areas and post what you find. Good luck. Make sure that you unhook your battery and for the love of Honda dont drive anywhere!! If you cant find anything tow it to a troubleshooting specialist. Your car CAN burn to the ground!
