corey_nethingcars Posted August 28, 2013 Share Posted August 28, 2013 I am new to the forum, but I do have a question. I have a 2008 LGT 5EAT. When it rains, or I was the car, it seems to me that the car stalls out when I'm at a stop/RPM's are low. Any ideas on what it may be? (The stall can be stopped when I give it some gas to get the RPM's just around 1k or above) Any help would be great! Link to comment Share on other sites More sharing options...
gimpydingo Posted August 28, 2013 Share Posted August 28, 2013 Soap on the intercooler when you wash it? But really, any mods on the car? Link to comment Share on other sites More sharing options...
corey_nethingcars Posted August 28, 2013 Author Share Posted August 28, 2013 It happens when it rains too, so it wouldnt be a soap issue. And no, no mods yet other than the front lip and eyelids. Link to comment Share on other sites More sharing options...
gimpydingo Posted August 28, 2013 Share Posted August 28, 2013 Hmm thought you might have a CAI or something. Maf got wet? Issues with compression? Link to comment Share on other sites More sharing options...
ProjectSega Posted August 29, 2013 Share Posted August 29, 2013 Yeah, maybe MAF got wet or dirty. Or maybe filter is dirty and clogged? Link to comment Share on other sites More sharing options...
ras06LGT Posted August 30, 2013 Share Posted August 30, 2013 I had a very similar issue in heavy rain (or after hitting a big puddle) where the car would almost stall out when coming to a stop, and had this very bad surging/power cut when cruising at anything under 50 percent throttle. Turns out the insulation on the front O2 sensor wires had broken right next to the sensor, allowing water to do strange things to the signal. My guess is when I went over 50 percent throttle or so it was kicking into open loop fueling and disregarding the signal. The faulty signal also must not have been long enough to trigger a CEL. After replacing it in preparation for a tune after my turbo swap, the issue has not happened again. Link to comment Share on other sites More sharing options...
gimpydingo Posted August 30, 2013 Share Posted August 30, 2013 After looking around ^ as he said, may also be an issue with the O2. Link to comment Share on other sites More sharing options...
corey_nethingcars Posted August 30, 2013 Author Share Posted August 30, 2013 I appreciate the replies. I'll have to give all suggestions a check. I'll check out the MAF/Filter first. Changing the oil tomorrow and also checking the air filter as well, once that's all done I'll see how it is and give an update. Link to comment Share on other sites More sharing options...

corey_nethingcars Posted September 10, 2013 Author Share Posted September 10, 2013 Sorry for not getting back ... I checked air filter, changed oil etc.. And still seem to be having the same problem - I've been thinking, however, I think the car may be running very rich.. You can smell the gas fairly well when the car is started/sitting and when you're on the gas a little (not like pure gas you'd smell if you spilled some at a gas pump) but that general smell.. Not sure how else to explain it. Link to comment Share on other sites More sharing options...
