2006 Tacoma 1GR-FE Engine Swap

I should have picked them up from partsouq for 150 since I know 100% they will be oem…guess I’ll keep the factory ones

 

Shop told me it was a grommet on one of the cylinders. It idles perfect now. However, while driving it home the partly blocked right CAT so hot it burned up the associated O2 sensor. I took the old manifolds off (problem CAT attached) replaced it with my JBA header and it'll run (loud) but it's sluggish. Getting codes P0031, P2238. I've got to get a new O2 sensor and have the headers welded with a new pipe fitting to connect the rest of the exhaust system. Could the bad sensor be causing the engine to be sluggish & sometimes backfire?

 

Yes it could. Don’t drive it until you fix that

 

I've been following this thread and hope you figured it out. Any chance, you know exactly what grommet (location, part number etc)?

 

I'll have to call and speak to the mechanic. Honestly, I wanted to hug him/her

 

I have a passenger side manifold if you need one.

 

So was the grommet the issue? Everything working normally now?

 

Grommet on one of the cylinders? Think has me very curious.

 

So, I got the exhaust repaired and I'm now receiving both P0031 (Bank1, Sensor1 O2 sensor) and P0301 (Cylinder 1 misfire). It'll startup fine and then it'll limit the engine to about 4K RPM. I did replace the O2 sensor.

 

swap cyl 1 ignition coil with the cylinder next to it and see if the misfire moves

could have a bad injector which would cause the lean condition melting your cat

 

I think I figured it out. I ordered the wrong sensor: Bank1, Downstream O2 sensor when I should've ordered the Bank1, upstream. Got a replacement on the way.

 

I have been busy with bodywork though. Check it out.

 

After all that work this thing is going to be niceeeee

 

Thanks bro! She's my girl!

 

Looks great! I'm thinking about doing my own repaint, but not sure how to go about prepping the fender flares. It looks like they're plastic but I'm not sure if they're painted. How did you prep yours? Sanding, priming, etc. Did you take them off the truck to get the rest of the body underneath them? If so, how difficult was it to take them off?

 

I had the same questions. I pulled the fenders off and sanded them. They were already losing their clearcoat. It was super easy after that. As long as you get the clear coat off, which mine was almost already gone. It will adhere without a primer.

 

Good to know, thank you! I hope you get all your mechanical hiccups figured out so you can properly enjoy it.

 

Got the correct O2 sensor. Unfortunately, now there is a massive oil leak coming from the front of the engine. I've found that this can be due to the PS pump?

 

so is it coming from the ps pump or the front engine cover? Sould be able to tell the 2 oils apart.

 

It’s gotta be engine oil. I have not seen any drop in the power steering fluid.
