I've got ES300 93 with 110 miles on it. Recently I've notices that engine lost about 30% of its power. I changed the oil it made no difference. I did fuel injectors cleaning using a special machine on previous oil change. Anybody has any suggestions ???

 

Have you intake manifold system taken apart and professionally serviced if you haven’t done it its time? Also valve cover gaskets head gaskets and oil pan gaskets might need to be replaced if you are burning oil or leaking. Change you PCV valve also. It could be a number of things. Have your Transmision vacume flushed and conditioned. Have your motor mounts checked? Mabey describe the loss of power in more detail to me?

 

oh and what special machine did you use? and you did it your self?

 

Whats up i have a 93 5 speed with 60000 my car felt slugish below 4000rpms i had my friend check the timing and it was off it was 8 degrees it should be at 10 but we brought it up to 12 the car is a different car it feels like i put in a computer chip were going to go up to 14 as long as it doesnt ping.

 

Guys thanx for the info. I'll check all that. I don't now what machine they used to clean the fuel injectors.

 

Todd50,how do you check the timing????

 

I find out tomorrow for sure but the car has 2 bolts that hold the distributor loosen and it turns we brought the timing up to 14 today it was raining here but let me say i was in 2nd gear doing 50mph i punched it and the car started spinning the tires with alot of wheel hop i didn't even rev it up that much just about 5 grand i had to let up i know it was raining but at 50mph and have the wheels spin it telling me theirs more power. Tommorow it will be dry i will let you know. Shift i'm doing this to let you guys know it s better than a $800 chip thats going to do the same thing the car idles fine the pick up is like a v8 and i get a mean 2nd gear chirp from the times.

 

Does it lose power on pull away? does it cruise ok? Does it feel like it is about to stall when you goto stop?

 

Hey Todd50 can you tell me how to change the timing on my 97Es300 ??? Do I need any special tools?

 

prolly one o them timing guns that shoot the light so you can adjust it right.

 

i talked to my dad after talking to the lexus dealer. and he says its ok for me to advance my timing. i am going to go someplace and have it done so as not to mess it up. i'll let everyone know what happens

 

This sounds obvious but sometimes things are overlooked. Did you check all your cables leading to the plugs? If they are loose you may be running on fewer cylinders than you should be.

 

hey someone please fill me in on like how you change the timing. like where it is, and what you have to do to the engine. sorry i'm still 15 and takin driver's ed in june. tryin to get some knowledge here.

 

yes help please. this is my first V6 car and i cant find the distributors

 

Sorry sir. No point in bringing back a 2-yr old thread
