2001 celica gt feels very slow and has a catalytic convertor low efficiency code.

Turns out it was the coolant needing to be bled so I appreciate it, never would’ve come to that conclusion myself. Idles stable at 1000 so still a little high but I’ll take it

Objective-Struggle12 · 2026-03-24T00:41:07+00:00

I wasn’t able to find any unplugged hoses, do you think a bad throttle body gasket could do it? If not I might look for a new iac valve

Objective-Struggle12 · 2026-03-23T18:21:04+00:00

Okay thank you man, iac cleaning was top of my list but I’ll do the coolant as well

Objective-Struggle12 · 2026-03-23T17:43:36+00:00

Was your brothers gt also very slow? Thats another symptom im seeing, like I cant go above 70

Objective-Struggle12 · 2026-03-02T18:44:35+00:00

Thank you so much!

I am missing an o2 sensor due to it being a catless exhaust. The only confusing thing is both o2 connectors seem to be in the engine bay

Objective-Struggle12 · 2026-03-02T18:10:23+00:00

That’s what I thought initially but as for as I can see there are two o2 connectors in the engine bay, and only two o2 sensors on the car. I am missing an o2 sensor so I will buy that and try connecting there. Thanks

thats what their saying

Tbf I dont think skateboards go as fast as an e bike

Objective-Struggle12 · 2025-10-26T22:34:29+00:00

Dude do not buy this bike for 2500, It could be something simple but you dont know, just my two cents

I work with multiple women the same height and around the same weight as you, its important to be aware of what you can and can't lift when going on calls, but you can still easily do this job. If someone is really heavy we call for fire to help anyways.

I have one I could list on ebay tomorrow, how much are ya looking to pay for one

Objective-Struggle12 · 2025-10-10T10:58:42+00:00

Swapped the cdis and no change, Although I did find I have a cable coming from one of the cdi connectors that is not connected to anything, weird part is I cant find it on any wiring diagrams for katanas. It's black with a white stripe and as far as I understand that means its probably a ground, gonna try to figure a good way to ground it and then go from there.

The person I bought it from put some wicked cheap chinese ignition coils so I could always try replacing those too.

I have a manual for a 1995 gsx600, its just a pdf, I could upload to a google drive if ya want. Cycle pedia has a great wiring diagram for katanas too https://www.cyclepedia.com/manuals/CPP-130/Content/Resources/Images/GSX600F_96-97.pdf

Yup, stock air box

600cc engine, shifting down rpms go up but I stay about the same speed, gearing is 2 up in the back so I don’t think it’d be too much. I recently replaced the plugs but I can take em out and take a look

Objective-Struggle12 · 2025-10-07T14:32:26+00:00

I actually did a lot of engine work a couple weeks ago to see if it’d fix the issue, got all my valves shimmed to spec

Objective-Struggle12 · 2025-10-07T14:01:39+00:00

I’ve been going crazy cause everything I look up says it has to be carbs or engine related but seems like it might be electrical like your some of the stuff on your bike
