Gdaylarry New Member 2 Member For: 9y 2m 23d Posted 26/06/17 10:21 AM Posted 26/06/17 10:21 AM Help Me!!!!!!! my turbo MISFIRES or hits a dead spot at 95km. It boosts perfect up until then and just goes flat for an unknown reason. If I brake for a red light immediately after the car will shut down. Every time it will misfire guaranteed!! I have just replaced all spark plugs and genuine ignition coils. I took it to auto tec and they put it on the Dyno and it misfired for them as well. They said I have to get it tuned for stage 1 and it will fix it. Way too expensive though. ANY IDEAS????

Look for any leaks or cracked plastic (if you still have factory plastic) in the piping from turbo all the way through intercooler to intake manifold. Also check fuel supply pressure. Depending on the pressure, it might be good on low revs, but starves engine of fuel on higher revs. If all of this comes out good, then I would shift my attention to transmission. I know that FG model deliberately misfires between gear changes in order to save transmission from brutal torque in auto transmission. I don't know whether they implemented this feature in previous models. Now, I would assume if this controlled misfire between grars is to become uncontrolled, then anything could happen, but nothing good, that's for sure...

I've had mine go into protection due to a lean condition/overboost and it shuts off a couple of cylinders and sometimes it would be temporary if I didn't run into the condition too hard and would come back but if it went all the way the car had to be turned off and on again.
Gdaylarry New Member 2 Member For: 9y 2m 23d Posted 27/06/17 12:29 AM Author Posted 27/06/17 12:29 AM Yeah that's what it seems to do but every time it will do it not temporarily. The dyno sheet said that it is running real lean and too much boost for the engine and that it has 230kw but apparently it has had no tuning. 1

I'd get it checked out by a reputable tuner and see if they can help you out. Yeah what mods does it have. Usually exhaust mods and intake or intercooler mods will cause this. Or even if they just turned the boost up without properly tuning the car.
