Car is dying at the stoplights. Engine runs smooth, but the car is just dying on me at lower rpms. i just replaced the opti two days ago? Anyone got any ideas. I am also getting a ses light. I am gonna try to get it scanned to figure out what it is. Thanks, Michael

 

sounds like you may have a leak after the MAF and before the TB. Check the elbow and make sure you have it on correctly. Does it do it in neutral?

 

sounds like a vacum leak to me... check all your vacum hoses at your throttle body and on your intake...

 

...and a stuck open EGR valve is like a big vacuum leak. Check it, too.

 

I am not sure if it does it in nuetral. I havent driven it since this morning, because I am afraid I wont make it back home. I am pretty sure the elbow is one correct. I ran my finger underneath it to make sure it was on and not bent or anything. I took it in like two weeks ago and i had them check for codes and I got a code 048 which they said was a maf code. The engine runs to smoothly for the maf to be bad. It runs like a brand new engine, other than the constant dying. I am unsure of the vacuum tubes you are talking about, and what should I be looking for. Thanks, Michael

 

Very true. A friend of mine has a faulty EGR that is progressively getting worse. His car feels like it wants to die under part throttle and at idle. Definitely likely...

 

where is the egr valve? I'll check that out too.

 

My Tech Page has all kinds of pics of component locations.
