new development started thursday night after a quickish drive home, parked up and it was stumbling BAD, like WRX bad blub-blub-ba-ba-blub unstable, turned it off and on again, no problem drove it friday/saturday fine, heaps on Sunday 'til on the way back from the beach at the end of the day it started again, but resolved later and got me from dinner to home without issue drove today to uni and it's fuuuuucked. warmed up okay, once fully warm it does the full blown WRX thing, struggles to get the revs up, but as soon as I get past 2.5-3k rpm it clears, and drives fine. definitely running on all cylinders when I rev it up, down low it's missing on definitely more than one. shooting black smoke out the back on idle really bad, multiple cylinder misfire that clears as I rev it up = flooding, badly still hear a vague put put out the exhaust when on the highway today when revs up feels fuelly as **** got some good advice from Emile, haven't had an opportunity to pull coil pack plugs etc on idle to try and work out if it's a few cylinders or all. i'm also running a set of injectors installed by a pack of monkeys that I suspect are leaking, as I've had to replace the o-rings on one already... thoughts? anyone had the same symptoms? -A
It'll never stop being funny Serriously tho, pull the injector connectors and try and work out which cyls are fuking up.
Maybe the same problem Mikey had, dodgy wiring to the coilpacks? Would explain the missing on more than one cylinder.
It doesn't seem like a broken wire, considering its symptoms of seeming to effect all cylinders and then no cylinders, and difference between warm and cold/day in day out. last time i dropped a cylinder it was broken wiring going to the injector and it was pretty damned consistent! new loom? i'm running on same modified loom for the last month
Knowing the history of one of your injectors, I'd bet a dollar on another farked up injector o-ring... or maybe two. AAA
Im putting my $2 on the injector connectors. You've upset them with your wiring tuck movement. Just give them a clean and the terminals a tension up and reconnect. Have had this happen (and still do every so often) where it will miss. Was due to me removing the connectors and fiddling with things. Have another look at it.
If it was a broken loom wire like mine, then it would be missing all the time, regardless if it's hot or cold :S
That's what I figured Mikey. Re injectors, that's what I was thinking as well. The car is already getting garaged on Thursday for, amongst other things, new injectors and connectors (550's) so I'm really hoping they're the issue.
I thought of that as well! Mine is already not the original (replaced by previous owner, big pink wrecker texta writing on it). Did some quick reading on it and failing FPCU doesn't seem to produce these issues? Thought it might be failing until it reached full 12v or something?
First time it happened... ...you turned it off then started again and it was fine. Have you checked ECU errors?... I've had the CTS play up in the past and restarting often fixes it for a while.
Initially 7+ odd years ago mine use to do similar things when hot or cold. Connectors were green, clean them and helped, (eventually replaced the ends for brand new ones) A year later when it started doing the same thing only when HOT, was a btch to find the problem, as all coils, cyclinders etc seemed fine. In the end it was the cold start. Think it was $90 from nissan and car ran perfect after that.
Probably right... ...he has had injector issues. But, how did turning the car off then restarting fix it the first time if it's injectors? Coincidence perhaps
I agree, it is worth checking the ecu temp sender unit and the fuel temp sender unit as well. If nothing else but to rule them out....
