Hey everybody! Glad to be apart of the lexus car community! Bought my 93 Ls400 from an auction here in Maryland and not long after my first Fully syn oil change, sparks and wires replacements it began idling roughly and also having issues accelerating. I was advised by someone to replace the idle air control valve and also the throttle position sensor.. now if I'm not mistaken there are two of these sensors? And to my understanding these part can be relatively expensive.. I Love the car and originally it was a gift for my old lady after her Rio broke down but this is our only form of transportation and it's now cutting off and I don't know anybody I can't trust with it. Any help would be much appreciated

I have no idea why the picture rotated, figured nobody would care its plain jane... Being that's it's a 93 I was told even an OB1 wouldn't necessarily help pinpoint the problem and that they'd be very hard to come by. Would a vacuum leak leave fluid on the ground? So far none where I park

To check codes no reader is needed. Vaccum sucks in air. So its not a fluid type of deal. The excess air confuses the engine management system, so it does things to adjust for it. And its going to be most pronounced at idle speeds.

So let me see if I understand... car was running fine. You changed the oil, plugs and wires and now it runs bad?
Don't know if I'd look for something new... possibly the wires and plugs you changed were not done right, or in the process you messed with another important wire/sensor.
Is that what happened.

I'm thinking something got disconnected during the work you did. One thing I found on this '92 we have is that the connectors are very brittle and vacuum hoses are the same.
