Newly Supercharged

[SpeedySolara]

I think I may have heard a little ping during idle but then again I was under a tree and it simply could've been an acorn. I truly hope I dont blow my engine cuz that would be a problem. I have yet to go to Toyota to get my car tuned. So far I went to Auto Zone and I have about 12 codes. Eight codes are cylinder misfire related, two are system 2 lean bank 1 & 2, I think a knock sensor, and one is for my O2 sensor. I put in 3 boost bottles and the rest 93 so it runs a bit better but it still fluctuates RPMs.

Do you have an aftermarket exhaust .....?

Congrats on the Boost .....

and what are your mods any SAFC ???

[CASTRO]

yikes thats a lotta codes. best of luck. the s/c really is a simple install and shouldnt cause those problems. Maybe quadrouple check the hoses and to simplify things, do the old hose scheme where it bypasses the EBC

[SpeedySolara]

The codes are P0300 - P0306, and some other ones in the 300's. I don't have any other mods (engine related) besides the supercharger. So yeah, all those codes are kind of freaking me out. Whats the system lean mean?

[Ilovemylara]

afr isnt correct.. more air than fuel...or too little fuel...

[Ilovemylara]

if the problem persists you might try bigger injectors, fuel pump etc.

I'm taking it to the dealership on Friday. Do you think they'll charge me an arm and a leg to correct the issue? More importantly, is this something I could fix?

[CASTRO]

i'd say check the boost arm actuator thing. I've read that some people's s/c came bent, siezed, etc etc which leads to problems like that. Make sure its smooth in motion and is getting enough vacuume/pressure to operate; again leading to the hose setup

how does your idle sound? sounds like a vacuum leak

[SpeedySolara]

It sounds normal but it revs a bit up and down.

[facevedo17]

Hey King you think it sounds like mines ...lol

I was throwing those cylinder misfire codes and lean bank 2 aswell ....

Speedy have you tried TB or Carb cleaner spray around the engine bay and see if the revs goes up if so u might have a def vacum leak ....

[SpeedySolara]

Facevedo17, how did you fix the codes and was it expensive? Right now I'm SH!TT!NG bricks but I'm also kind of pissed. I don't have any sort of exhaust or tuning modifications, just the supercharger and everything is OEM. Please let me know what you did to correct the issue. Thank you.

exactly

[facevedo17]

You can tackle it different ways . your only mod was the SC ..no fuel pump..? did you change your spark plugs ...? and if all is stock I would look into a vaccum leak somewhere

In my case I don't know yet because I haven't really fixed anything yet .. But then again I have Jim fuel filter ,lines upgrade, fuel pump, and safcII , Injen CAI/Ext , Y pipe and custom exhaust with a leak somewhere ....therefore I have to look at all those different things.

In ur case and sounds like its strictly Vaccum recheck them hoses .....Im still new at this aswell. When I met up with the guys in the rockland meet they gave me some good tips and what can be causing my rough idling too..

[facevedo17]

As far as correcting the codes they vary ...for me when scanning the car it will give me like 12 codes and sometimes 3 or 4 and thats what I get now usually haven't scanned it in a while now
