I have a 2003 E350 15 passenger van that the ac went out on. The compressor actually had a hole about the size of a dime in it! I replaced the the compressor, the accumulator/receiver drier, and the orifice tube/expansion valve. I also flushed the system. I also made sure that the compressor had the correct amount of new oil. I was going to drive it to the mechanic to get the system recharged. The van idles just fine and sounds like it should. The problem is that when I put it into drive, when I hit the gas the engine stalls/dies. It will start right back up but as soon as you his the gas it dies after a second or two. Thoughts? What am I missing? Any input would be appreciated.

 

Disconnect battery ground, then disconnect C128 electrical connector, wait 10 minutes, then reconnect just battery ground and start up your car check and see if it dies again, if not, go for a test drive for 10 minutes or so. Note when MAF is disconnected, you will get a CEL and your van could be in limp mode, that means it can be lack of power, your objective is to find out why it starts and dies, a bad MAF has the exact symptom. When it goes bad, forget about MAF cleaner since that's for preventative routine cleaning only. Of course if the C128 has corrosion, clean it to avoid bad reading without replacing the entire MAF.
