OK I have a 1993 del sol(150 000km) with a jdm d15b vtec swapped into my car with about 45k and car is stock minus a short ram intake and never winter driven.

Anyways, when i hit a big puddle the car dies, it restarts about minute later. Ive checked the grounds and there all corroded and green. I think the spark plug wires are original with the swap and dizzy is newer. also plugs are newer. What do you guys think i should check? I'm going to change grounds and wires for sure. Any input or suggestions would be greatly appreciated.

thanks guys.

 

or common sensors that could do this too?

 

thinking from the ground up...

crank position sensor- i don't know if the D15B has one like the D16Y does, but if so have a look at that. if you're splash shield and/or timing cover are broken or missing this could be plausible.

primary O2- ECU looks at this for mixture adjustments. i suppose that could cause the engine to stall.

anything higher than that, you just need to stop crossing rivers.. haha.

i would maybe expect to see a CEL on if a sensor were shorting out though. maybe it is a grounding issue still. be sure you're dist. cap has it's little rubber o-ring seal. and maybe give the ignition a good tune up. couldn't hurt..
