Hey everybody! I'm new to the forums and new to the Lexus world all together. I've own infiniti g20 and quite a few Hondas! I have a 93 gs300 and I'm excited about having it. I've had it for about a year. Have not had the chance to drive her because I cannot keep her idling. Hoping to find the problem soon. As of now she is green with staggered 20" wheels and new leather seats. I'll post a pic tomorrow!

welcome to the board.

Is the engine stock or you have done some work to it. you can post your issues with the engine idle and i'm sure folks will help you figure it out. or you can do a search on the forum as well.

WELCOME! I also had an idling problem when I first got my car and I cleaned out the TPS, throttle body (make sure to plug the coolant underneath and cover spark plug galley from coolant) and the ISCV.

If you need any instructions on how to do so just ask. There are plenty of us with service repair manuals and I can link you some pages that might help.

Car looks great, a great project... better than when I got mine!!!

Welcome to Club Lexus! You car looks good! I had some idle issued when I first got my car. I had to adjust my TPS and I also cleaned my idle control valve. I found a tutorial online, if I can find the website I will post the link for you.

Thanks everybody! The car is rough and still needs plenty of work. Joewitafro, I would like a manual. That would help me out quite a bit. I honestly have used the search button so many times. I've saved everything that I have searched. I Will try not to ask any questions because I haven't looked through every page yet. The idle issue WAS fixed. I needed a fuel pump!

I bought a Walbro fuel pump. I've heard people say that they are loud! Well this one isn't not. I can barely hear it with my seat still out of the car. I haven't even put that metal cover back on yet and I still can barely hear it.
The fuel pump never primes but for about a week or so the car still started.

Now I'm back to a no start. I think I flooded the motor because I pulled my plugs and they smelled like gas. My exhaust also smelled like gas! It was my fault because I would go outside to crank it and as soon as the engine started, it would turn it off. I was told that was the reason that caused it to flood.

So now I have a new set of plugs, wires, distributor cap, rotor, IACV seal, valve cover seals, and throttle body gaskets and intake manifold gasket. After I clean the throttle body and IACV and put everything back together, I will see if that helped...I hope lol

AlphaStran

Thanks man. That would be great. I will say that I have cleaned the IACV but I may not have cleaned it all the way. Didn't really see a good tutorial on the cleaning or the TPS.

I've looked on YouTube for the throttle body removal but it was already removed and the guy didn't seem to sure about what he was doing.

joewitafro

I have the manuals but they are hosted on an FTP site.

if you PM Me I can instruct you on how to access this, you will need an FTP program manager to access the files.

houndawgbp

Got it from him and hosted it too lol

AlphaStran

Thanks again for your help!

So I started the throttle body removal...I've never seen so many spider eggs in one place(the car sat in somebody's back yard for almost years)

Here is the back of the throttle body...looks really dirty

Here is the front(might be hard to see)

Here is the back after I cleaned it



Judging by how nasty the intake manifold is, should go ahead and clean that as well? I have all the gaskets for it. Or do it even matter?

I wouod just spray some throttle body cleaner in there and use an old tooth brush to scrub it out.
