View Full Version : new na-t misfiring issues

04-15-2013, 10:19 PM
I've got a 93 JDM 2jzge recently t61 turbocharged. Problem is on idle there are almost constant misfires, and pretty major losses of power through-out acceleration. Not only does it mis fire, but also idles and runs on the lean side. Typically idles around 16 when the engine is hot. Because of this it has been barely driven, not much fun for someone who wants to enjoy some fresh boost.

Also timing is set at 10 TDC.

Map Based (JDM)
Apexi SAFC (original 5 nob one)
AEM Wideband
Stock internals

Please help me get her running

If its running on 16 afr and misfiring there must be an ignition issue. I wouldn't be driving it at all if its misfiring on idle.

The turbo setup shouldn't make a difference to the running of the engine until boost, a stock ECU can handle the turbo without pressure. Try removing the Apexi and see if it idles any better.
