Im at work so im going to make this quick. P0036 code for past week which i believe is o2 sensor? So this morning i go to start car and its idoling rough as hell going from about 400-900 rpm so i give it a little gas n it stops and idols normal BUT i had -17 vac. Second time this happend since i threw that p0036 Last week so obv has to do with the code. Please leave me something for when i get out of work. Thanks you brobalts

 

Bump

 

I got you.

P0036 is definitely O2 sensor.. Rough idle is probably about not getting the right a/f ratio because of that sensor..

-17 Vacuum isn't terrible (at least I hope, mine sits at -15 when I first start it then settles at -20-22). You should just have to replace that one O2 sensor and it'll be good..

 

if the car was cold it would be at 17 vac easily. Doesn't settle down to 20 unless out of cat warm up mode and the AC isn't on.

 

P0036 is a downstream 02 sensor. It has no effect on fueling its job is to determine if the cat is working or not. Sounds like a bad cam phaser to me.

 

My cat warm up is tuned out btw. And for the cam sensor wouldnt that thro a cel? (other then the p0036)??? & the code is for the "heater control circuit bank 1 sensor 2", im assuming that is the downpipe o2 correct?

Thanks

 

Any other codes pending when you scan it? How is your oil life? Cam phasers do not work well if the oil is sludgy or the wrong weight.

 

No other codes, 1/1. Oil was changed about a month and a half ago and I actually did make the mistake of not putting full synthetic in it.. But i dont think tht wld rly be the cause. It was of cource 5w-30

 

I hope you flushed that crap out and put full synthetic back in. I can't imagine regular oil doing well in a LNF. Lol

 

ummmmmmmmmm about that

 

my car does this rough idle. and ive had no codes. it sits at about 17 vac i think its a cool idle the guys at the car meet(old schools) think its cammed.

 

Got the same CEL, interested on possible fixes
