Starter on my 92 went out back in 2009, little did I know how intensive the replacement process. Luckily mine was just burnt contacts which cost me $5 to replace.....unluckily my car has never run correctly since and sits now 9 years later. It runs but has a miss I cannot pinpoint.
The plastic on all the wiring was so brittle many connectors either disintegrated or broke to some degree. I had to replace all the injector plugs. The worst part was the intake was so warped it wouldn't seal.....and it's a known issue since there is a warpage tolerance in the Lexus manual.... DOH!! Fixed that issue by taking the intake to my machine shop and fly cut it all perfect.
Once the vacuum leak was fixed it still did not cure the miss. Since I had to take it apart all over again I decided to replace the timing belt, belt tensioner, water pump, both distributor caps, rotors, plug wires, and spark plugs. The engine has perfect compression across all eight cylinders even at 138K miles. Engine is perfect but the car still had a miss so all I can assume is it's electica.
I never was able to pinpoint the issue so the car just sits. I've been working on and restoring cars since 1977 and I've worked on hundreds of cars and this is the first one I was never able to identify or correct the problem. I can't see how you guys can work on these old Lexus cars these days as all the plastic under the hood turns to dust, and my problem was 9 years ago.
I'm sticking with my classic cars, they don't have electronics to fail and leave you with a perfectly good car mechanically that is now useless because of the failure of a part that a not available or simply not traceable.
Now I need to just get rid of this car, sad because it was a nice car at one time.
