Hi, I have a 1990 LS400 4.0 V8 with 256K miles.
A couple of weeks ago where I live was flooded and the car was upto the top of the headlights in water. When the water dropped enough for me to get to the car I started it and drove it to higher ground. The car drove ok for a few days then the transmission started slipping. I couldn't get out of first gear and had to crawl to the mechanics. I parked it and left it overnight. The next day the mechanics checked it out and everything was fine. It started and drove with no problems. Then about a week later I had to brake suddenly and turn sharp right into a parking lot. The car was hesitating a little a few minutes before then but after that it has no power at all during acceleration. The engine revs ok but a little rough. I can floor it or accelerate gently, it doesn't matter which, the car crawls but will eventually reach the speed I want. It's changing gear a little roughly too. I usually have to back off on the gas to get it to change into the next gear but before this happened it drove beautifully, no slipping or any sign of a transmission problem. In fact it shifted smoother than most cars I've driven. Have I lost my car or is there something quick and cheap to repair it? I am short on money and can't afford to take it into the dealership and pay several hundred dollars just to find out how much more I'll have to pay to get it fixed. I do have a good mechanic that we take our cars too but he admits he knows very little about Lexus. I was told that when braking I probably moved some water from somewhere into the engine and I need to change the oil, air filter, spark plugs and then find a steep slope to park the car facing uphill and rev the engine. The engine will rev to red line but when in gear there is nothing, it will rev but it takes forever to get any speed. Could it be possible that the exhaust is blocked with mud from the flood water even though it drove ok for a few days and the engine starts and revs ok? I'm kind of grasping at straws here and hoping I can find the magic fix and save my baby. I really miss my car and want her running smooth again. Please help if you can.
have the same problem?
