9.YOTA.4

I have a 1994 toyota pickup with the 22re, i had the exhaust run on it in december and it has 2 1/4 pipe with no cat and a backwards glass pack yed of into two big tips, about a month later the truck started acting funny when u started it like it was missing but after a couple seconds on the gas it idells out fine. i haad to put a throttle positioning sensor on it a while back but it still acted up when u first start it. Then a couple weeks ago i put an ect sensor on it cause it would set the code for a second then it would go off. but today after driving around for a while i let the truck sit for bout an hour and when i went to start itu p it actd like it was missing like it does when u first start it but when i reved it up it didnt stop until a couple mins down the road. one of my friends said it smelled like it was running rich. any help would be greatly appreciated.
Thanx Cody

Start with the basics... plugs, cap/rotor, wires.

its not good to run a motor with no cat, it can burn up valves over time. but like he said start with easy stuff first.

Blue 89 Runner

How you figure ??

9.YOTA.4

thats what my dad said but would that make it run rich

Gotta start somewhere, might as well be the easy and cheap stuff to get at, take note of the plugs as you pull them... if you do I guess. Once a plug gets gas fouled its shot, no matter how good you think you cleaned them !

O okay man i will try that.

with no cat it will tell the o2 sensor to run richer in witch makes it run hotter and that will burn up valves. i have known 2 people who took out cats and they both over time did burn valves in there motors.

Unless he has a California spec truck, I am pretty sure he only has one O2 sensor, which doesnt care if there is a cat or not, and running lean is what causes hotter temps and burnt valves.

i had one o2 sensor and it was in front of where the cat was

I have somewhat of a reverse problem a few months ago i noticed after my truck warmed up when i pressed the brake the motor would surge but i kept driving it bc i didnt know wat it was since then its stopped doing that idk why...i noticed one day i was merging on the interstate and if you run my truck full throttle it bucks and jumps/sputters i though fuel problem or ignition anybody ever have the same issue lmk thanks mine is a 93 with 22re 5speed

when you put a new throttle position sensor on it did you adjust it properly with feeler gauges and an ohmmeter?

gmc2258

i never replaed the throttle sensor...i was told that wasnt it because it only did it when the brake was pressed...

Running with no cat will make your exhaust smell different.

But like Blue 89 said. Start with plugs wires cap and rotor. Those are easy and cheep things to try first

I would love to hear more on this burning valves by removing cat and how a truck with only on o2 that is front of a cat is going to make it run rich when the cat is removed?

well i went to go start the truck up this morning and it would start at all so i had to drive my moms dodge to school but on the way home i got plugs wires rotor button and a distributer cap and it runs like a champ now thanx guys

Drive it for a day or two and check back ! How did the old stuff look ?

9.YOTA.4

well the truck has been running great now but i got a noise in the front driver side i think its the bearings in the hub cause the cv axial is loose
