ok heres the story last sunday i was driving home from a meet and my sedan started missing mad like when it had bent valves anyway i got home ran CELS it was throwin codes for 02 sensor, IAT, and IACV, reset the ecu (took out the fuse) before i even started the car the same cods came up so i figured the ECU is bad... put the stock single cam ECU in and it stopped missing still throwing code for 02 sensor and IAT tho i know 02 senor being bad will cause the car to bog.... but im not sure if it will cause the car to bog so bad that when you are able to drive it at 3k rpm it sounds like its breaking up ive been tho nothin but problems since i swapped this car.... think being out in 95degree weather is fried my brains lol any help

 

update Just hollowd out the cat revs up ALOT better might still be some in there because when i whent for a test drive it took off decent but at like 3k rpm still is breaking up as if it was turbod then when i stopped it was doin the same thing where it was bogging when give it gas


And admin thanks for the warning and not just taking it down didnt mean to come off as a d*ck

 

Any1?

 

heres a vid of what its doing once i figure it out the problem ill tell every 1 what it was http://www.youtube.com/watch?v=XBQPuSOvmbA just incase someone else is having the same problem

 

is it even tuned?

 

Its not turbo its all motor i was saying it breaks up like it was turbo...

 

well what ECU are you using? and did you tune it for a B20 (since b20 manual ECU's are extinct)

 

It's a ls ecu fixed it new 02 sensor and IAT
