Callum-Glanza Posted December 14, 2016 Share Posted December 14, 2016 Recently rebuilt my engine as I shot a rod through the block, now running fully forged internals.Bought the Glanza a month ago and the same problem seems to be occurring with the new engine.If I floor it, it offers no power but if I feather the throttle on an off I start to build boost and then goes well. Also been told that the black smoke coming out the exhaust is pretty bad, which I'm guessing would be the excess fuel? Only recently the cars been popping every so often, the EML also flickered a few times. I have changed the dizzy, arm, leads, plugs and coilpack, the problem still persists any help will be greatly appreciated!Also checking vacume pipes from off the turbo on the weekend, just a bit stuck now if it's not that?

Stu Posted December 15, 2016 Share Posted December 15, 2016 Assuming your using a stock ecu here but if the check engine light flashes on there will likely be a code stored. Check what it is and let me know. Map sensor plumbed correctly? Whats the engine/turbo setup? Quote Link to post Share on other sites
Callum-Glanza Posted December 15, 2016 Author Share Posted December 15, 2016 I was informed that an original ecu was put back in place of a flashed ecu, but I don't know if that's true or not. I'all get on to that asap, currently running a ct9 hybrid, with 0.8 boost, been told to set the actuator higher, closer to 1.2Thanks for the reply! Quote Link to post Share on other sites
gorganl2000 Posted December 15, 2016 Share Posted December 15, 2016 do as stu said.....also check that your oxygen sensor is connected Quote Link to post Share on other sites

Stu Posted December 15, 2016 Share Posted December 15, 2016 If the fueling is all over the place the last thing you should do is wind the boost up.Let us know how you get on re codes. If its flashing the check engine light on it could be a boost cut (especially at 1.2bar) but there is likely other codes stored. Quote Link to post Share on other sites
Callum-Glanza Posted December 15, 2016 Author Share Posted December 15, 2016 I'll get back on Friday night. Suppose what I'm trying to say is, is it okay to drive the car with the fault? Have no confidence in the car, but I need to run it :\ don't want to cause further problems. Will I benefit from a rr session? Quote Link to post Share on other sites
Stu Posted December 15, 2016 Share Posted December 15, 2016 Just check everything is plugged in properly ie map sensor, water temp sensor on thermostat housing, injectors. You could actually try unplugging the TPS as seeing if it works any better but thats a temporary fix. I'd avoid anything but cruising around until you have it sorted.

Callum-Glanza Posted December 15, 2016 Author Share Posted December 15, 2016 It wasn't doing this before the engine change so hopefully it's just a loose connection somewhere. Sorry but what is 'TPS'? Thanks haha. No driving about till it's done!✔️ Quote Link to post Share on other sites
Callum-Glanza Posted December 15, 2016 Author Share Posted December 15, 2016 Not sure is this helps but lugging, like a strong jolting happens in the lower revs, not sure if that's down to me or not just happens when taking off? But if I feather the throttle it goes away, dunno if it's because I'm actually going through the revs or if this a problem? Quote Link to post Share on other sites
Stu Posted December 16, 2016 Share Posted December 16, 2016 TPS is the throttle position sensor, its mounted on the back of the throttle body. Quote Link to post Share on other sites
amirs Posted December 16, 2016 Share Posted December 16, 2016 check for vacuum leakshad similar issue and was a broken pipe off the intakehad similar issue and was a broken pipe off the intakedoes it sound rough on idle? Quote Link to post Share on other sites
Callum-Glanza Posted December 17, 2016 Author Share Posted December 17, 2016 Found the problem! A vacuum pipe from the sensor to the intake has fallen out the housing, back running good now! Quote Link to post Share on other sites
triple j Posted December 17, 2016 Share Posted December 17, 2016 Must of being the map sensor pipe, she would run like a bag of shit without that. Quote Link to post Share on other sites
