so tonight i was out and after my car had been sitting for about half an hour after some mildly spirited driving, i got in, started it, put it in reverse and felt the car shudder like it was going to stall out...

i just gave it some gas, backed out and started driving to see if it continued. it didn't.

i just had an oil change today and had my rear section replaced with the hks... should i be worried? i know tomorrow morning first thing i'm going to check the oil since it will have had a chance to sit all night....

 

If it felt it was going to stall, it sounds more like an engine thing. If it didn't throw a 'Check Engine Light', I'd think it would be okay. Might just be a 'one-off' condition, but keep your eye on it.

 

Actually, don't know if this is related, but the same thing happened to me right after Boris installed my Coupe Midpipe. Happened that one time and after 7K miles, hasn't happened since.

yeah i haven't experienced it again... i hope it doesn't come back....
