My car is reading between -16 and -17 in vacuum at idle. Is that low?..I could swear I used to see approx -20

Thanks!

 

I see -20 to -22

 

i think i see 15-20.. i'll check today for sure though

 

......

 

18-20 hg

 

Does anyone get around 22-22 after boosting for probably 3-4 seconds then it creeps up to 16 or so? Or does yours generally "Stick" at whatever value.

 

Wow. I wish I was between 15 and 20. Heck, even 10 would be nice. I'm at TWO thanks to code P1136 throwing me into limp mode. Maybe one day I'll figure out this code...sigh

 

I usually spike to 21-22 and level off at 18-19.

 

^^ same here unless i have the AC on..

 

P1136 = Too Lean. Not sure if you changed anything. Quick way out of limp: disconnect battery for 10mins, reconnect then put car to the "ON" but not turning the engine on. Let it sit there for about 3 minutes. The trottle body will realign.
