I can only seem to find 3 spark plugs on the drivers side where are the other 3 ? It's the 3.4 v6 can anyone help ?

There are three on the diver's side and three on the passenger side. On the passenger side you need to remove the air intake tube between the throttle body and the air filter box.

Waskillywabitt I know it sounds crazy I just can't see them even when I try to look under the air tube but once I remove the tube they must be there

Wait, there's 6 of them?

I I took the air tube off at the trottle body and te throttle body and it's flap in caked with gunk , could that be the cause of cylinders misfiring ??

lavigne25

And I removed the air tube and you said they would be right there well I still don't see them all I see are probly coil packs unless there under that and I only see 3 plug wires

lavigne25

Will carburetor cleaner do te same job as throttlebody cleaner ??

michael0584

Yep only 3 plug wires, the other 3 are right under the coil packs, remove the coil packs and you can access them.

Ok thanks man , I'm trying to figure out wy that throttle body is got gunk all over , I'm wondering if that's the cause of the misfire or is it the bad plugs and plug wires causing that throttle body to be dirty , anyone know ?

michael0584

Check your pcv valve, pull it out and shake it and make sure it rattles. It's on the passenger side valve cover near the front. has a hose on it that If I remember correctly goes straight over into the intake.

lavigne25

Ok will check that , could that cause misfire ?

Where the heck are the other two? Dude who sold me mine said it was a V-8......

Apologies to the OP - I guess if you've never seen coil packs right on top of the plugs before they must look weird, and where the heck is the dizzy so you can follow the wires back to the hidden plugs? No offense man, just something to chuckle about.

Throttle body is all gunked inside, or outside? Inside? Yeah, they can get that way. Search for cleaning instructions. Carb cleaner'll work just fine. Outside? Dunno. I do know it's not from your electrical system though...

edit: ah, reread the thread: inside. is it just running rough, or actually pitching a misfire code?

badattitude

I should have mentioned the coil packs. Sounds like you found them.

Be sure to use Denso dual electrode plugs. People report problems with other kinds. I just put 6 new densos in my 4runner and it runs smooth.

michael0584

Not sure about the misfire but could contribute to the gunked up throttle body. I would clean everything up nice. Get some trottle body cleaner, try not to get too much down the throttle body. Then see how it runs. Do you know when or if the plugs and wires have been changed? If cleaning doesn't help, I would install new plugs and wires. Start with all the maintenance stuff first since it probably needs to be done anyway.

Wow that is an epic post.

lavigne25

I just changed the plugs and success thanks everyone for the advice , simple fix one plug was Burt , could of been from the trip across canada pulling a trailer

lavigne25

And yes I used 6 denso plugs from Toyota dealer , runs really smooth now. My 4runner has 300,000km I do and oil change every 5-6 thousand km with castrol fully synthetic and with the new plugs my truck sounds like it's new when I run it

BMcEL

That's a lot of meters!

Good to hear it's running right.
