Ok When at idel the engine has a bad miss' .You can even hear it in the Exhaust , going putt puttt puttt. Car Shakes.
This happen after I had a complete Tune up.. We thought maybe we got some bad wires , but we have replaced everything 3 Times ( including Dist. cap ) and still no help . PVC , Fuel Filter has also been changed .The car is a 92 ES . Any thought? It cant be bad gas , Re-fuled twice already using different service stations . The engine has No Codes.

Also wanted to state , You dont feel the Car missin' when driving , Unless you come to a stop... And on the last dist. cap we had on , I touched one of the wires that was plugged into the dist. cap and got shocked to hell and back , but with the 3rd. Dist. cap now on , I dont get Shocked when I touch it.


I feel like Screaming ! Went to the mechanic today . Drove the car for 25 miles with it hooked up to the Scanner . Nothing . Changed the Fuel filter again. Had the fuel system professionly Cleaned .. Still missin' .. Checked timming and ignition .. still missin' Found the big hose that comes off the air filter was busted to peieces .. Replaced that with a new one.. Car ran great for 10 miles . No Miss .. We'll now its back ... You can hear it bad in the Exhaust ...Any one have any thoughts?

As for the plugs , wires , dist.cap. All working 100% , There is no Miss fire in those .The car does not back fire . The missin' is at idel or when u come to a stop , but not when in motion..

 

timing may be off? just a guess, cause all the things uve checked were ok...did u have a lexus dealer do it ? or a private mechanic?

 

I had my private mechanic check it . I am going to the lexus dealer tommorrow...Joy o joy , here comes the bill ..

 

You should always use Denso spark plugs,I'm not too sure about the 92 ES300,but the ES300s with the 1MZ-FE need to have Denso platinum Spark plugs with twin ground electrodes,or you will get a missfire!!

 

Did you get fuel injectors serviced in the first round of your tune up?
Odd thing happened to me is that I experience misfiring, vibration, serious exhaust note after this service and a second fuel injector cleaning is what fixed it.

 

Where can you get those Denso spark plugs at?

This is what I am having. What was the fix?

 

engine misfire due to the bad spark plugs... it has to denso brand... also be sure to check your coils too because this happend to me once and it was a bad coil.... i learned it the hard way at the lexus dealership.. costed me $398.00... Good Luck!

 

I changed my plugs and my fuel filter and the car is still missing. It will idle fine and then miss pause 30 seconds and then miss again and then again then fine for a few more seconds. So freaking wierd! Does anyone have any ideas? Would a coil do this?

 

yea coils can affect the way it responds test each and every one of your coils

 

Forgot to give a Update . Had 6 new injectors installed . 4 of them was bad. Of course , It costed me $600.00 just for lexus to figure out the promblem and Then $169.00 a piece for injectors (bought 6) ...talk about ouch!

 

Vacuum lines, vacuum lines, vacuum lines!! Check them twice. These things have a million of em. And yes a 92 or 93 with a 3VZ should also have Densos with 2 electrodes

 

ya i had a cylinder misifre, and it came out to be the coil
