i had a low idle and my neighbor who is a mechanic came over and set my timing forward 10 degrees. dont know how its done but it made my truck run a hell of a lot better.

Have you tried adjusting the idle speed? It's the large, front-facing flathead screw near the top of the throttle body. Just screw it in when motor is hot to reduce idle speed. Spec is 800 rpm but 800-900 is okay - I set mine where it idles smoothest. If the screw bottoms out and it's still running, you have a vacuum leak, or perhaps someone adjusted the throttle stop position (which is factory-set and should never be touched), or something is preventing the throttle from closing fully, or your cold idle bypass valve is stuck open.

Heh, go for it. if you're willing to make the investment. could always go with a cat back. but I can guarantee the gains are much better with headers.

That probably could be it.Quote:
This is all a mystery to me right now... its been pretty chilly in NOR CAL lately... so morning starts are always high. but i'll pay more attention to it at a stop light more often. it seems fine. its running exactly how it was before I did the headers, if not better. I'll run a diagnostic on it... never done it before but eh, gotta start somewhere. I'll letcha all know what it is.

Timing belt sets cam timing, not ignition timing. The 10 degrees mentioned is the base ignition timing spec set by rotating distrib (with jumper set in check connector). (If you think there could be over 70 miles on the timing belt, it needs to be replaced.)
Really, just try adjusting the idle speed screw - any coin will work.

Adjusted the Idle screw... its back to normal /shrug. Like I said before, its running perfect. not too sure what the engine light is on for though. i'll figure it out. I hooked a ground wire back up to where it belonged. Forgot to wire it back up after the installation. but other than that. everything seems fine.
guess we'll find out what the engine code is.EDIT: Yeah. I need to get the timing belt/water pump and driving belts done. also want to do the CV joints and radiator. lots of mechanical things need to be done. Im plannong on doing the timing belt, water pump, radiator and driving belts all in one. Knock it all out while im working in that general area.

would you like a 0-60 video? I can make one for whoever would like to see if theres a difference, if I have enough interest in one? /shrug

Would be great to see what it can really do. Some things you can do to make performance as good as possible:
If your timing belt is old and tired, probably best to replace it beforehand - very high revs are tough on old belts. Let the new belt break in 500 to a thousand miles or so before your run. If you can do your ISR before the run, that might help a bit, but won't make a huge difference. Calibrate your speedometer by maintaining exactly 60 miles per hour on a measured mile - should be 1 minute, if not, calculate correction to find what your speedo reads at 60 miles per hour true speed. Check your tachometer with a good shop tach/automotive multimeter so you don't overrev the motor. Clean throttle body if needed. Verify that when pedal is floored, butterfly valve is all the way open. Make sure cooling system is in good shape. Fresh oil and filter to protect motor - a full synthetic 5W30 from Red Line or Amsoil would give a little more hp, full synthetic 10W30 would protect the motor a bit better, would still give a bit more hp than a mineral oil of the same weight. Use a Toyota 90915-YZZD3 filter for better flow. New Denso plugs, cap, rotor (& wires if needed). New air filter and also new Toyota fuel filter if not changed in last 100k miles. Add a bottle of Red Line SI-1 Complete Fuel System Cleaner or CRC "Guaranteed to Pass Emissions Test Formula" to your tank and run it through before doing the run to clean your injectors. Those two have polyether amine in them which is about the only effective injector cleaning chem. Then fill tank (only half way - don't want to add weight) with 91-93 octane. Try to find a gas with 0% ethanol (E0, or non oxygenated) as the alcohol will kill your performance. Try Sunoco, maybe Shell. Set base ignition timing to 14 deg btdc with jumper set. Gives noticeably snappier throttle response - some veezy owners run this timing even using 87 octane, but a higher octane will reduce likelihood of detonation which would cause computer to pull timing back down. After the run, 12 deg is a bit more conservative and runs fine with 87 octane, and is probably a better all-around base time for this motor than the 10 deg spec. But when getting an emissions test, set it back down to 10. Remove all excess weight from vehicle - for at least one run, go without passenger. Air up tires to 38 front, 36 rear Drive it gently before the run - you want it operating temp but not too hot. Choose a cool or cold day (should be easy this time of year). Make the run at or near sea level. Except for first shift, run rpms up to 5100-5200 before shifting (or up to red line if you really want to wring it out). First shift can come @ 4800 - 5000. Have fun and be safe!

i'll do it whenever possible. probably on an on-ramp... at one of the carpool meters or whatever you might want to call it, just so im doing in a 65 miles per hour speed limit range.

Looks good, but wow... I didn't pay that much for my whole truck. I know my exhaust is in bad shape, muffler/pipes/everything else full of holes, but honestly I've gotten used to the noise. Besides, once I hit about 30mph or faster, Mr. Super Swamper wins that particular noise battle anyways

lol yeah. I paid a butt load for it
but I love every bit of it. And I can guarantee, with this set up... the noise of the exhaust will drown your Mr. Super Swamper noise. I can have my stereo at 30 ( usually what I keep it at, got a ticket for it being at this limit ) and I can hear my exhaust growling. I love it nowadays I keep the stereo volume at 5 ( just enough to hear it ) and just listen to my exhaust. heh

Well, basically with my current "set-up" if you can call it that... I'm running open headers. It's LOUD. Bugged me for a while but I got over it pretty quickly. Have plenty of other things to fix on the truck before I worry about little things like exhaust. (we don't have emissions here anyways).

yeah. emissions here suck :/ lol I wish I could run with out a cat... but eh, thats california. Despite the cat, I love the way it sounds... very throaty. I had a guy with a 2wd 4runner at a gas station ask me if I had a boxer motor in it...? I dont think it sounds like a boxer at all... but eh, everyone has their opinion
honestly, it sounds like a 3.4, to me.

0 - 60 miles per hour video...
Where's it at? I'll subscribe to this thread till it comes on. BTW..nice job and the feeling that goes behind the tiny cuts and sraped knuckles and multiple hmmms' trying to figure it out as you stand there... is priceless when you have that much enjoyment in the end.
![]() Question though- did you have to lift the engine at all? -Ted

![]() Yeah, the only problem I have with it now... is that its so loud that stupid ricers like to pull up next to me and act as if im racing them... just like the other day, im doing 65 on I - 80 and a trans am WS6 comes flying up next to me, slows down, gets next to me, looks at me, and floors it... I just turned to my buddy that was in the truck the me and laughed... lmaoLift the engine? nope. never moved anything except what was required... intake, vacuum hoses, manifolds and crossover. EDIT: by the way, CEL is on again. came on two days ago. o2 censor is acting up again... I actually am thinking about going back to my stock Cat. the High flow makes a weird noise until its warmed up, also which is kind of annoying. So yeah, thinking about the stocker.

making a 1-5k rev video, fly by, and a 0-60 video here in a few. Just keeping everything updated.
