Hi,

Im new to the forum. This might be a long story so I will start from the begining.

Just got myself a 92 Lexus LS 400. I bought it wrecked. Thought v8 rear wheel drive, built by toyota, I cant go wrong.

The car was hit in the front, just at the top of the bumber, breaking the drivers side headlight and pushing the radiator back just far enough to touch the fan to make it stop.

Well, when I got into the car, it was running fine, no problems, after driving the car for 30minutes, and one burn out...(just to see )The raditator hose hit the drive belt, thus leaking all my coolent out. I was able to repair the hose with a maglite bought from wal-mart. I then drove the car the rest of the 200 miles home with out a hitch.

The next day, I wraped a chain around the front core support and jerked it out a bit, looks good to me, the fan is now operational. Drove another 45 miles no prob. Picked up a friend for lunch, we was completely floored I was driving a lexus... I had to show him how well it could bust the rear lose, so I gave it some juice, well.......burn out #2 was as bad as burn out #1. This time, the radiator bounced back and hit the fan, draining the coolnt agian. Radiator is toasted. My friend had to get back to work, I figured no prob, I can drive maybe one block throught the mall parking lot and leave the lexi there. Didnt make it to his work. She just died.

I figured being as smart as a lexus is, it might have an automatic shut off or something if I ran out of coolent? Well I left it there for the night.

I bought a used raditator swaped it in the parking lot, filled it with some coolent, and started it right up.

It was running smooth at 1000rpsm. I wanted the thermostat to open so I could finish filling the coolent, pressed my foot on the pedel and all heck broke loose.

The car was jumping rpms from 1000 to 3000, then she died, and would not start agian. At this point my check engine light is on.

I thought maybe one of the distributor might have gotten wet? Well I had it towed back home last night.

This morning, went out there, and poof, she started right up. I let it run for a bit at her own warm up idel, and then I held it at 2000rpms, was doing great for about a minuted when it started to cough. let it go back down to its own rpm. Ran smooth, no check engine light. It ran here for about 3 to 4 minutes and then it statred coughing and had a pretty bad idel. I shut it off. and now it wont start agian.

Any ideas? Places to start looking? Anyone have a smilialar problem? I dont have any wheels and need to get this thing back on the road asap.

Thanks in advance for your help.

What are the chances I got one of the distributor or a coil wet with anitfreeze? Just a thought?

 

check for fault codes

the throttle body and idle control valve might need a clean out but knowing the fault code will help you a lot

 

Hi, Im getting a code 13, anyone else ever have this problem? What do you do to solve it?

Thanks agian,

-Chad

 

code 13 suggests that the ECU is not receiving a signal from the distributor. Check the distributor and it's circuitry, ingition coils, and/or lastly the ECU itself. My guess is exactly what you thought and that antifreeze got into the distributor. Woul;d not hurt to change the ignition coils as well.

 

To each their own...but wth were you thinking when you wanted to peel out twice on a car that hasn't been fixed properly?!?!?! Maybe you should wait till you fix it properly before beating the living daylights out of it.

 

VSS sensor ( crank sensor- vehicle speed sensor ) possible connection in wiring or loose sensor

 

Yes as has been said , most probably a loose connection , go over all your plugs from the coils down and give them a spray of WD40 while you are at it .

 

Hi, thanks for all the advice.

Yesterday I took more apart, double checked the timing, its good, checked the engine speed sensor with the multi meter, it was good. Im putting everything back together tonight, and we will see.......

-Chad

 

Ok, so I put everything back together, and now I have no spark. I replaced the caps and rotors, Im wondering what I did wrong. It looked pretty strait forward to me.

This car is getting the best of me......

Now where should I be looking?

-Chad

 

Hi,

The car runs great for like 5 minutes then I get a code 13,

How do I get this?

How do I fix it?

-Chad

 

Did you check the ignition coils? If you're not getting spark in either the distributor or the rotor, then the ignition coil is the next step to check...either that or the ECU as someone else suggested.
