Hey All,
so been having dilemmas the last week and i thought i'll get some ideas of what could be happening.
last week when i started the car in the morning the revs just jumped to 1.5k rpm down to 500rpm and it keeps jumping violently around 500-1k rpm, i drove it to work and it was popping/misfiring and bopping/chocking when i accelerate, so first thing i thought was coil packs and i've had cat issues awhile back so they both came into mind, the weirdest experience was when i accelerated and the car doesnt move, the revs always seems to struggle to move after 2k rpm and its not until i down gear that it blows a cloud of black smoke and then it starts to move again, after that i accelerated nice and slow to get to and back from work, when i got home i had a look and found
- oem coil pack was cracked so i replaced them with splitfires
- cat was clogged - replaced it with an xforce cat.
- spark plugs were very black - replaced them as well
- been driving with boost setting (off) 8psi (apexi pfc)
the popping from the cracked coil packs gone and the smoothness of the rev range when i accelerate is back.
thought i didnt have any issues after that but when i changed the setting to (A or B about 12psi-15psi) the car again struggles to move when i accelerate and occurs only around the rev range of 2k rpm to 3k rpm, its feels like its chocked, pops like misfiring and blows alot of smoke during this time, everytime this occurs you can smell this electrical wire/plastic burn smell? not that rich smell every time it clogs and struggles to move.
with the boost off (8psi) the car seems to not have that problem (been driving for 1 day and as far as i know it drives fine with boost setting on off) and drives like there is nothing wrong with the car...
this problem seems to occur always when i turn the boost setting to either A or B 12psi-15psi.
i have not tested it enough to say when it doesnt or when it does.
because it happens in the morning and even if i just turned off the car for a few hours it happens and sometimes it doesnt occur and drives fine.
Im quite stumped with whats happening and want to know if this has happened to anyone before? the explanation is all over the place so you guys must excuse me for that.
Cheers guys.
