was or was not closing onto the plug all the way? if you clamped them together to resolve the issue, i'll assume you meant was not closing onto plug all the way, and in that case i will def check that as well when i install my NGK wires. Make sure they grasp the plug nice and snug.

As for the RTV gasket goo, do you guys put that on the uppper intake to throttle body?

New wires shouldn't have to be tweeked, by anything more than your hand.

dannydavi 04-24-2007 10:47 PM
oh yeah they shouldnt... but you heard dudes post up there, he had to tweek his... so it couldnt hurt to check.

ya new wires aren't supposed to have to be tweaked.. thats what I thought and I got the misfire.. for this reason is why I dont like the MSD. yes, it was that the clamps inside the boot weren't fully clamped onto the plug.

RTV... I didn't put any RTV on my throttle body to intake manifold.. I simply purchased a new gasket from Toyota and installed that. It works fine.

thanks alot man. Is there some sort of "rule of thumb" for putting RTV where gaskets go, or is it just something you gotta look up in a manual? cause when i took it off it looks like there was some sort of gasket sealer used is why i thought of buying some and using some, but now since i have to take it off again... i'll make sure to go straight gasket... sucks you have to buy those things in a whole set.. :(

a whole set?
 
I just the two throttle body gaskets for each side from Toyota.. like $15. and just use a scraper or flat-head screwdriver to scrape off whatever old gasket might be on there.. also while the throttle body is off, clean off the throttle body plate using some brake cleaner.

i did do the cleaning cause it looked yucky in there, as for the gaskets, i guess i was looking in the wrong spot... well not really, cause i get the entire(upper and lower) intake gasket set for 10.97 at kragen or napa.

Ok so i fixed the problem, i took out all the plugs to check gap and what not, and two of the plugs were broken on the insulator part, once i cleaned out the holes really good, got new plugs, put it all together... it ran really smooth. Me Happy :D... so it probably wasnt the wires... but at least i got new wires now..

To fix it, I just took some long needle nose and clamped the inside together, by the way I HATE MY MSD WIRES. I'm switchin to factory as soon as I get the time. Don't waste your time with aftermarket, stick with Toyota, at least in my opinion, hell if you want the MSD wires you can have em from my car for free.. haha.
Wow, i can tell you're not a mechanic. Yes, genius, it IS crucial to gap plugs. Why do you think the gap specs for every car known to man has the spark gap specs under the hood? It's there for a reason.
