I have a 95, 4cyl 2.7L Tacoma. I went through the automatic car wash and the undercarriage water jets stalled my truck out...now the truck lacks accelartion and stumbles under load.
i replaced air filter and checked for moisture at intake, there was none.
When i checked the distributor cap it electricuted me from being wet, 2 of the spark plug wires going into the cap were wet, and the electric connector plug feeding the coil inside the distributor was wet.
The truck runs and drives but spits/sputters when i accelerate and has no power at all

I want to replace the distributor, but my QUESTION is if the distributor/coil got wet and was faulty wouldnt the truck not start or run at all?? I feel pretty confident the distributor is where the problem is and needs replaced, but i want to make sure that is what the issue is based on affordability and eliminating cheaper potential causes. ALSO Can i replace just the coil part of the distributor or is it all 1 complete unit cap, rotor, coil???
I am a 22re guy and this is the first 2.7 4cyl ive worked on so i am kinda still on that learning curve hah. Any advice or pointers would be great. Thanks

 

Well, you learned a good lesson. Electricity, especially high voltage, and water, don't get along very well. Wet plug wires will bite you every time. Once you got everything dried out, did it still bite? Did you check inside the dist cap for water? A micro crack?
The quick, easy first step would be a new cap and rotor. Does that stop the trouble? How about new plug wires? If the sheathing on them is starting to break down, they'll leak electricity. You can actually do an easy check of them by looking at them in the dark. Do you see any mini-lighting bolts out of the plug wires? Is there water in the ends? is one of the ends loose?
Is the dizzy plug still got water in it?

Lots of easy, cheap, checks you can do before you go onto the more expensive tries. A real good idea is to put a small dab of silicon dielectric grease into every electrical connection you can find. Plug wire ends, dizzy plug, coil plug, whatever. It keeps water out, prevents corrosion, etc.
Check every ground you can find. Bad grounds can be a real headache in electrical systems.
Are all the spark plugs working properly? They can be easily checked by pulling one at a time, and touching the ground electrode, the one curving up and over, to the metal of the engine. You should see a strong spark in the plug's gap when you do. Make sure you use insulated pliers to hold the plug or YOU will get bit good.

I don't know if any of this is any help, but it's certainly cheaper, quicker and easier than replacing the dist entire.
Good luck!

Also check for chafed wires at near the O2 sensor for the cat.

 

Is the check engine light on? There may be codes stored even if the light isnt on.

 

I replaced plugs and wires and today ordered a cap/rotor + an ignition coil and will be replacing them over the weekend, pretty confident the issue is in the ignition coil.

Its been almost 10 years since ive been on this forum and i forgot how informative and well done it is. Thanks all 😎

 

I sure did. And to never use the automatic car wash. The reason i went to it was because my buddy gave me a free wash ticket. I knew it was a bad idea when i was waiting in line to go in... 😬

 

After a week or so of doing tune up maintenance i discovered the distributor mounting gasket needed replaced and oil was getting into the distributor. I hauled my boat today as a test drive and the trucks running great.
