Misses, exhast smell while running,took sensers off still runs and misses

Frank, have scanned and diagnosed by a good technician, estimate for repair. "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."

you may have a plugged fuel filter as you don`t say if you have changed it. also have your fuel pressure tested with a gage, it should run about 36 lbs pressure if its multi-point fuel injection or run at about 15/18 lbs pressure if its a throttle body.

try looking at the engine while its running at night. look for electrical sparks around the coil,dist cap, wires,etc. check for broken or missing ground wires. plug wires could also be bad

Sounds like a vacuum leak. Spray carb/throttle body cleaner at all fuel and air intake areas ie; intake manifold to heads, throttle body to intake, all vacuum hoses, etc. Work the throttle to keep it running or have someone inside doing it. You will know if the carb cleaner gets sucked in somewhere. That will be the location of your vacuum leak.

most cars have four, or five there are two hiding in the top of the Y pipes. did you miss them?

you might have a plugged up catalytic converter,check and see how much pressure is coming out of the exhaust pipe, does it feel like the air is flowing out the exhast pipe smooth or just a little bit. you may have to take it to a muffler shop to have them check the pipe pressures before and arter the converter..

Check your Catyletic convetor it may be plugging you exhast. If there is a bad smell @ the tail pipe it's more likely, another sign is a rattling sound from the convertor area when the engine is still not @ running temp. If your exhast is plugged up you will have poor performance @ higher engine RPM's

Sounds like you missed connecting something back up. The Knock senser won't make it not run it'll just not let it run at peak power. The OHMs on the sensers just need to be close and your old senser may be just fine. The senser watches a reluctor wheel go by. Did you put it back on? did you put it right side up? It'll fit backwards but it won't line up with the senser.

There is most likely an engine oil leak that is leaking on the exhast that runs accross the bottom of most toyota engines. Valve cover is common

o2 sensor mixes the difference of fuel and air. i would think u probably need a new coil pack or distributor cap.
