New to the forums looking for some help with my 1991 ls400
had the car for about a year, pressure washed the engine which now I know was a bad idea.
So was driving home started misfire took it home checked spark plugs distributors any sensors that were visible blew them out with compressed air distributors weren't wet at all but after going through the whole process made the misfire a little bit better but still misfired
When at idle it misfires and then when you start to drive it will bog out and then regain power. While driving the misfire goes away and then comes back while driving will also lose power when driving and then regain back to normal

Anything helps thanks

So if it just started doing that after washing it I guess you figured out the problem. After washing it hopefully on a nice hot dry day, let it sit 24 hours before starting it, the longer it sets after washing the better.
