Does any body know how to adjust the timing on a Tacoma with ignition coils instead of a distributer. Cuz i know how to do it on a distributer but i have no clue on is how to do it wit ignition coils.

its a 97 Tacoma 4cl 2.7L if that helps

That's because you can't, the ECU controls the timing.

Red Neck Bill

so would i half to take it to the dealer or a auto shop to get it done?

MTL_4runner

Hehehe.....no, they can't do anything with it either.
You can't adjust the ignition timing, period.

Why do you need to adjust it?

i entered a rev off at school and came in 3rd and after that it back fires sometimes when i shift from 3rd to 4th and my dad said that it was the timing i don't know if he is right or wrong what do yall think it is.

WTF is a rev off? Do you just sit there and rev your engine?

MTL_4runner

I was wondering the same thing....

So you basically started out with the truck running fine, entered this rev-off and now it backfires under load? and how's the idle?

Sounds more like you might have slipped a tooth or two on the timing belt.
You also could have burnt a valve or two, but you'd need to do a compression check.

They must just sit there and tach em up, just till the valves float, which is right before the the block becomes windowed?

I guess your name is fitting. Who revs the crap out of a 4 banger truck? lol

That sounds like the only probale cause.

And a rev off ehh??? wonder what thats like...
Do you guys see who can hold it at red line the longest or what?

MTL_4runner

.......conjures up quite the mental image doesn't it?!

ChickenLover

You mean 'Timmying'?

HaveBlue

Wow, what a great audience.

It is possible to at least check the timing to see if its off. Do you have a haynes manual? It tells you step by step in there...

I have one so if nec. I can scan the pages up for you to see. Like MTL_Runner said...it is possible you slipped a tooth, I'd lean more towards the burning of the valves or something if its backfiring though.

For the record...you have a timing chain...not a belt.

Thats about all you half to do to win and i also found that the crack in the exhaust manifold i welded when i first got the truck. it has re cracked around the weld and all the way around.

Honestly, whats the point of the "Rev Off" ???? See who spends most money repairing afterwards?

Edit: What does the winner get?

MTL_4runner

A ride home in someone else's car?

Stevo3

but he said he placed 3rd.

marko3xl3

So you basically line up and just jam the pedal until you get to the rev limiter and hold it there until your engine dies? How did you come in 3rd without your engine blowing up then?
