so im a day away from having to smog and register. i have a few issues. last friday i got a blip will driving and then a wicked idle surge and a huge hesitation off idle. checked the codes and i got 157, 189. so i warrantied my aftermarket maf and noticed the car started to idle like it had a cam. then about 2 days ago my CEL came on for about a minute and went away at the end of a 20 minute commute. pulled the code and came up with 189 again. so today i swapped left and right o2's and cleared the codes. on my drive home same thing with the CEL so i checked the code and got 189 again so its most likely not the o2. where two now? any help would be appreciated. oh and BTW this is just more bad news in a gang of bad news in the last 2 or 3 months. first the cobra hood i traded had some extremly amature repair done to it before it was painted so when i stripped it i found quite a bit of work, then i find out that the roof has been replaced in the car so althought its got a clean title its been rolled and chopped and then today while swapping the o2's i find that the water pump is puking. awesome.

not necessarily. But it can cause your surging idle.

mos def a vacuum leak.
small update got the water pump in perfectly and appears to be legit. did some testing the narly camed idle goes away if i fire the car with the maf unplugged. im thinking this maf is calibrated for 24 lbs injectors is just faulty.
