SS Sudden Rough Idle & Stuttering Under Load After Service. Need Help Please!
Hi Everyone,
My Ve SSV has been running perfectly up until I got a service last week.
The only engine mods it has are extractors, high flow cats and dual 3 inch exhaust.
As a result it had the engine light come on but has continued to run fine for 8 months now.
It was due for a service and they noticed the engine light, I told them it was from exhaust system.
Anyways after the service when I picked car up they had cleared the light and during the short drive home everything was good.
I then haven't driven it until all weekend until today. Everything was fine until 20 mins into my highway trip it started stuttering under load
regardless of gear. The engine light came back on now and when I came to a stop it then ran rough at idle.
Car is going back to dealer to check it out.
It is also on the same tank of petrol as before and after the service.
Does anyone have any idea what could be the problem?
My car is 2007 SSV, Manual, Runs on Premium, 31,000kms.
Thanks for any help!
Did u put ur exhaust on? Or a shop? Should of had it tuned when u put the exhaust on.. As for the rough idle It sounds like they've forgot to put the exhaust sensor back in..

Shop put exhaust on at start of year and has had 8 months of worry free motoring with it on. Dunno why exhaust would have been touched it was just a usual service and as for the engine light they said they just hook it upOriginally Posted by phat_6ltr
to the tech 2 and clear the code.
Fair enough I had something similar happen and it was the exh sensor, did the shop dyno tune the car after they'd put the exh on?
Slightly off topic, but it sounds like you didn't get a tune after installing the exhaust - did you notice much of a difference in performance without the tune? I ask because I'm thinking about getting high flow cats with stock headers and slightly modified stock catback.
Nah just ordered in everything and installed it for me that was all. Was waiting until I got an OTR before getting a proper tune done.
Yeah that's probably it then, it would have run ok till Holden mucked around to get the engine light off.. Gonna need a proper tune done mate..
Yeah a bit little bit more go and alot more sound. Also better fuel economy. But yeah to take full advantage I'd need to get tune.
Would likely be hard to tell the difference with just high flow cats and a modified stock cat back though.
Are you trying to keep it fairly quiet?
Nah... lol- I heard the cats are the biggest restriction in the stock setup. Hoping to be selective with my $$ and mods
Same thing happened to mine it was just a plug lead make sure all your leads are siting on the plug and coil properly.
Holden told me it was from when I had my headers fitted that they never put one if the leads back on and it
Burnt the lead out but I still got it covered by warranty which was good.
Yeah heard about the leads getting burnt before so checked for that but all clear. Hopefully it will be something silly like that so it'll be all good and not get charged a fortune

Clearing a code wouldnt cause the car to run rough.
Was it a straight basic oil and filter service? Any extras done?

Yeah just a basic service.
Car was taken in this morning and it has come back in perfect running order now just like it used and at no cost to me.
It was found that # 2 HT lead wasn't fitted properly and had become detached from vibration etc. They refitted and cleared code / engine light.
Any idea what a HT lead is?
