Team -
It all started with a battery change... I guess the computer forgot how to keep the engine going when I had the battery out. The first few times I started it she would just die right away which is the norm (see my sig for the basic few upgrades). But she kept stalling for like two weeks. If the engine wasn't warm it wouldn't stay running without help from my right foot. The first week or so of driving it she would stall out at stop signs as RPMs dropped it was as though there was no idle at all and the motor would just turn off. That went away thankfully.
So now she won't stay alive until she's warmed up. If I take my foot off the gas to keep her going RPMs drop to 500 and she chugs and glugs for a bit until she dies completely. Once she's all warmed up and been driven a block or so she's peachy.
Codes:34-insufficient EGR flow or Defective EGR pressure transducer senor (wtf?), 66- mass air flow sensor fault, below minimum voltage.
Both are continuous memory codes, haven't run a KOER test.
I looked around the site and found some bang up articles on these codes. First thing I did was cleaned the MAF sensor - I need to go easy on the K&N oil, the element on the sensor blackened the q-tip I cleaned it with. That seemed to help a bit. I haven't tried cleaning the EGR yet because I haven't had time to get that deep.
Could a wonky EGR really cause a low idle and stall? I wouldn't have thought it could have such an effect. Tomorrow I'll take off the EGR and have a look, also I'll clean the AIC and change the plugs (its been a while). What do you think of the EGR, my symptoms and getting a new MAF sensor? I also noticed that my MAF was rotated a bit so that the sensor wasn't exactly on top... must have vibrated out of line - would that matter?
Thanks everyone.
