Austin's Supercharged Mid Travel Build

Thank you! Can't wait to get the bumper on.

 

Still can't seem to figure out what the issue is with my truck, and it's still not throwing any codes. In neutral / park the engine works great, even if I rev it up, but if I try to take it for a drive it stumbles and is pretty much gutless.

So far I've cleaned the MAF, cleaned the throttle body, replaced the throttle body, replaced my up stream o2 sensor, and checked both my cam position sensor and crankshaft position sensor with a multimeter. The fuel pump, spark plugs, and wires are all very new as well.

Not sure where to go from here. Might just take it to a mechanic.

 

So, I gotta ask. When was the last time you changed the ATF?

 

I had my local Toyota dealership change the ATF about 5 months ago. Also just recently had a trans shop go through my transmission and they said it's in great condition.

 

I figured, but never know. Does the RPM get bouncy when it stumbles?

 

It seems to be pretty consistent with what the engine is doing. If the engine bogs down, the rpms drop, and vise versa.

Also, I forgot to mention that the problem happened over night and didn't have any symptoms leading up to it.

 

Any clunking noises?

 

Not that I can hear

 

It really sounds like something is binding, or the torque converter is jacked up.

 

I agree, hence why I thought I had a transmission problem in the first place. Otherwise I would think it would have thrown a code by now.

Going to take it to a mechanic soon, hopefully they can figure it out.

 

Took the truck to a mechanic today and they found the issue to be a clogged catalytic converter. Should be fixed and ready to go on Wednesday

 

Huh, how long did it take him to find that

 

About 45 mins

 

That's been me all day^

 

Not bad! Lol I feel like that would be a hard one to find

 

Yeahs it's definitely a weird issue. When I originally took the truck to a trans shop thinking it was a trans issue, they though it was a bad cat. It wasn't throwing codes for a bad cat so I didn't really think it was the issue. I tried to pulling my cat off to test it but couldn't figure out how to get it off. They have an odd set of studs on the flange. Anyways... glad to finally have it resolved.

I wonder how long they have been starting to clog, and if I will get a lot of power back with new cats?

 

I would say there will be some power back. Clogged cat affects the back flow

 

I would think so too

 

I can't believe you didn't get a code for that. Good news is its getting fixed though!
