Hi all,

Latest problem...I recently changed oil and filter, and I replaced my warped air filter box at the same time (heat from turbo = wavy plastic = loose clamps). I transferred over the MAF to the new airbox and everything seemed OK.

Over the last couple days (about 10% of the time) when I hit the accelerator from a stop, I experience a 1-2 second lag before any response from the car. It's not like a transmission slip sensation when the RPMs increase and then the car lurches forward. Instead, nothing happens for the first moment I touch the gas pedal...then all of a sudden the car wakes up and it's business as usual. There is a dead spot in the pedal and I'm not sure if it's caused by fuel starvation, electronic faults, or other gremlins. The throttle position sender is $500 and the MAF is $300, so I don't want to start throwing parts at this problem. No check engine lights or pending codes by the way. Throttle cable slack seems appropriate...moves gradually just as a helper actuates the pedal. I know these MAFs are delicate. Could moving it to the new airbox jostled it enough to kill it? The vacuum hoses near the air filter still look undisturbed. I'm really lost and annoyed by this one!

Here's a thread of someone with the EXACT same problem...no solution ever reported by original poster.

E300TD Hesitation

Other info if helpful...fuel filter, plastic fuel lines about 10-30K miles old. Fuel tank strainer original. Air filter brand new. Diesel purge 10K miles ago. Transmission fluid 20K miles ago.
