Did you cover all of your electrical components including battary? If you didnt then often times if you get all your electrical connectors wet then it could cause things to act up. Letting them fully dry out before driving it again may fix the problem.

When washing the engine bay, I always cover all electrical connectors with plastic the best I can and I also cover the air intake just to be safe.

the car turns on fine, i've started it up 4 times since the wash and let it run for 5-10 mins, the longer i leave it running, the more the car feels like its losing power?!

Are any warning lights coming on? You could try to disconnect the battary, dry the terminals (probably shouldnt be wet anymore anyhow) let it sit disconnected for a lil while and then reconnect and see if that helps. Not sure if it will though.

the warning light above the tach.. and also the temp warning light?
but i will disconnect dry off, and re-post if problem still occurs, thanks for the help.

OK, I would let it sit disconnected for at least 30 minutes or so. If you dont mind me asking, where are you at in Germany? I just moved from there about a year ago. Did you buy the car in Germany?

I just started it and like it run for about 10 mins. same thing happened. light above the tach stayed on the entire time, as soon as i put it drive to go around the corner, the light next to the temp came on. really dont know what to do know, really confused and kinda pissed off now.

im stationed in Vilseck and I bought the car from another soldier here on post.

Yeah, I know about the rain there. I was at Ramstein from 2006-2010 but I made very frequent trips down to the Graf/Vilseck area. We used the dropzone on graf for airdrops all the time.

Let me know what happens when you are able to disconnect the battary.

I would say that we need to find out for sure what those warning lights are. If you cant tell then maybe someone else can get on here that knows or can look at their car or owner books. I dont have my car or books available right now to look at. You could also see if any codes come up.

i know the one by the fuel and temp gauge is the ABS light.
as far as the other light is an ! with a triangle around it, thats about the tach

Well the light that you described sounds like a general coution light. My supra is in storage in the states (I didnt want to bring it to Guam) so I cant look at it. I bet if you checked for codes you would get something.

ok so. took distributor cap off, no water, dried it anyways. disconnected battery, wiped of terminals; nothing. waiting for night to start the engine to see if i could see sparks coming from any of the plugs, nothing. connected E1 & TE1 to run check, no check engine blinks; tried connecting them with the ignition on, and connected them with ignition off then turn on, nothing.

dont know what to do now. going go buy a new battery and see if thats the problem, doubt it but its worth a try.

if anyone has any other suggestions, feel free to share please!!?

It could be a vacuum leak. Perhaps your spraying in the engine bay dislodged a hose. Pressurize your intake to find the leak.

ima noob, so how would i go about doing that?

i think it might be the distributor cap and the spark plug.

the plug in the middle of the distributor cap, the one that goes off other then the engine, is damaged. the i disconnected, the male portion was stuck inside still. so going to buy a new distro cap and plug. plus, try the spraying for the brake cleaner.

ok, so a mechanic here told me to either take everything apart or just drive through the problem.
I don't have the time, nor money to take the entire engine apart, so I just continued to drive through the problem, now no more rough idling. car runs as it did before.

thanks to everyone that tried to help, its greatly appreciated

I'm hoping that it was, but then again it could been that the engine electronics were just wet and over time dried off. but if it does continue, i'll re-post..

also, do you know how to install digital gauges? i just recently purchased Drift's digital speedo, tach, and fuel level gauges and hoping that I install them myself..

Just like you I washed my engine bay,

car ran fine when i started it, no issues but once i left the car running it begins to die. I checked my fuses and everything, and when it came down to the problem, it turned out that the alternator got wet and i ran it without it drying out properly. This burnt out the coils and hence the car would die randomly or loose power. I changed my alternator and everything works fine now. I hope this helps... sorry read that you solved the issue, I'm still sure it had to do with your alternator...

cheers

Well I just replaced the entire unit, but once I opened the old alternator the coils were black so it was definitely the alternator coil that was causing the problem

Oh you meant alternator coils. Your previous post sounded like somehow the ignition coils had gotten burned out.
