I had a day off yesterday, the weather was being it`s usual learning disabled self (meaning not a nice May day). Anyhow, I got a little bored so I went out to the garage to see if their was anything I could do to my RX. Didnt need an oil change,I just rotated my tires, so cross that one off the list. Hmmmmm, I konw!
I`ll do a Seafoam de-carbonization! So I pop the hood, pull the pcv valve (yes the motor was already warm) grab my trusty can of Seafoam, and start the car to begin the process.
Everything went as it should, I let it suck in about a 1/4 to almost 1/2 of the can, (I have drive by wire) so I went back in to up the throttle some. As soon as I hit the gas, it made this KNOCK sound, like the knock sensors were going off real bad! So I tried to turn it off......Well, it kept on running, You know, the old pre ignition thing? So I turned the key back to on, continued running as usual. I thought to my self, man this thing must be carboned up bad! turn key off,,,same thing, kept going, put it in drive, I thought to myself you cant keep on going now! Three times This happened until it finally, or should say, RELUCTANTLY slowed to a HALT! All I can think of is it must have had some real carbon issues going on.
Anyway, I take it out for a spin, people are looking at me like Hey,that Lexus just blew an engine! Smoke out the back like no tomorrow. I go up on 33 South, run the [censored] out of it, and it finally settles down. Mean while the knock sound I heard before must have been the good ole knock sensor`s pounding down the ignition timing as low as it could make it because this thing was running like [censored]! After driving around for a little while, it slowly started to get back to it`s normal self. Keep in mind, I did this to my 01 RX too, and although it set off the cel for cylinder miss fire, it never pre ignitioned like this one did. I was really surprised about that. So far, it seems to be running very well now. I plugged in my scanner, no pending codes or anything.
The only reason I did this is because I remember how it helped my other one gain a little more throttle response. And because my fuel millage has been down lately, last year I was getting 19mpg`s, and lately only getting 17mpg`s Runs fine, no codes, air filter is good, must just be this wonderful fuel we have these day`s. I just thought I would share this with you guy`s,as I value your idea`s/comment`s on the matter.
Thank`s
