What have you done to your Tacoma today? 1st Gen Edition

Ah yeah, I did the same except it was an eightball...

Your idle is dead center for the type engine you have, you can go a little lower but it won't stay there for long. Keep messing with the ECU, good bet your sensors will start failing - fast.

 

any chance you have the paint code from them? Im gonna be doing mine pretty soon and have thought about asking them to add a little tint to darken it up, or at least get it slightly more blue than blurple![/QUOTE]
Sorry i just ask them to make it a little darker, but I’ll ask if they have the code.

 

From my understanding it’s fairly instantaneous once contact between hot and ground has been made… Maxbore.

 

Dead center as in normal? Nothing normal about 1100 RPMs in park.

 

Hopefully, the new IAC fixes it. Make sure to disconnect the battery while you swap them out.

Also, while you have the TB off, take a close look at the butterfly. Shine a light through it from behind. See if you can see light coming through around the edges between the bore and the butterfly.

 

Mine always took a bit of driving to get it to settle down. But if it was doing this before you reset, then I suspect something else is afoot.

how are all your vacuum lines?

 

If you don't use it, you'll lose it man.

 

this actually works, put some seafoam and rev that bitch out on the hwy

 

You clean the maf? Have any pending codes? Oem iacv? clean it. Check the butterfly opening. Check the plunger on a cold start, see if it sits right.

 

MAF was cleaned recently. IAC is not oem. About $120 off rockauto. And what the hell is the Italian tune up? I’m either not educated on this fix or just missing out on the inside joke lol.

 

if get an oem iacv, such an important piece to the reliable taco, I wouldnt cheap out on that piece. The italian tune up was more used in the days of carbs, I still believe in it for cars thats have sat for awhile or an owner that never would go past 50mph cus they never did hwy speeds, or when you out a cleaner you hust rev it all out of the system. You dont have any pending codes?

 

Here’s what I’m starting to think….
Back when I originally replaced the old IAC in December, I never reconnected the PCV hose that connects to the TB and drove it like that for almost two days before I realized what was going on. Had a bit of a weird idle to it but still drove fine. Is it possible that since I drove it like that for two days I forced the computer to adjust itself accordingly and just hasn’t been able to adjust itself again yet?

 

Just the P0420 that comes and goes

 

If you plug it back in and you disconevt the battery and remove the fuse aswell and reconnect might go back after a tank of gas

 

Could be a bad cat, o2 sensors, exhaust leak, bad gas, ive even seen a can of seafoam in the tank will fix it for that code.

 

only use oem

 

My 95 idles pretty damn high.., i need to look into that once I have the bed on it.

 

I’m just investigating this idle issue. I’m not really tripping over the p0420 code at all. Thank you tho!
