A/F/R Problem

[CMF_mycra]

guys here is my problem....while driving EVERY TIME heavy throttle is pressed my A/F drops straight to dead lean and hesitates like no tomorrow.

However when every time released, it shoots straight to rich then and while cruising sits perfect in between.

any ideas?

have you got an induction kit fitted mycra ?

How are you checking it? If it's a cheap gauge I would not trust them at all. There mainly for show. Get a wideband meter on it and have a look. Might be your O2 sensor maybe?

i replaced fuel pump, ngk o2 sensor, pump relay pretty much everything related...

do have a povo autobarn gauge, but the difference between now and b4(last week) is tremendous. can dramaticly feel the the power loss.

this is the reason why im on my 4th cg13tb...

could it be a damaged ecu??

 

[CMF_sikK11]

Could be maybe. I have a stock one I think also a throttle body that was workin fine when it came off our car. Also still got the Autronic LoL you know you want it. 1200 delivered

mine tended to gain nasty flatspots when run without the factory snorkel fitted mycra (GA16 one on mine)
you might get mad induction roar and a bit more top-end with a cone tho

yep once again we are reminded some factory things are done for a reason hey

No you can keep the factory ac wiring. Looks to be sold to radiolite now LOL just waiting on cash. But have a stock ecu somewhere and tb if you want that

 

[CMF_mycra]

will do... might look into pissing that map sensor off and run a sr20..
in a while

so is the a/c on a different separate loom? does that mean i can run the nistune kit and keep the a/c yeah?
