Rough acceleration no codes.

I have a 02 V6 Escape that is spuddering and hesitating when accelerating. When I go to accelerate the engine sputters like it is not getting enough gas. My engine light has not come on and I put on a reader from a parts house and did not get any codes. The engine does not do it in park when I rev up the engine, only when driving. The engine does spudder a little while at a stop light. The transmition was rebuilt at 184,000 miles and I am currently at 213,600 miles. The tranny fluid is clean and the tranny shifts normal.

I replaced the air filter and a friend ran starter fluid thru the air intake, but the engine still hesitates and sputters on acceleration. There is no vacumm leaks that I can hear and did not notice smoke coming from the air intake manifold.

I love my car and got to make it last. Any ideas or do I need to be using a shop scanner?

I would remove and inspect the MAF. If it gets some dirt on it, it will make the engine run terrible. Also check fuel volume and pressure if you can.

Update

Thought I would give an update. After i changed my air filter my car started shaping up (it was very dirty, stupid me

LOL). I also changed my spark plugs, the COP boots and coils, and put in new air intake gaskets. After i changed my spark plugs I noticed the breather hose elbow joint, that connects to the plenum, was collapsing when the engine was running. I replaced it and no more additional problems. I even got 22 miles to the gallon after all that minor work!! I was only getting 19ish.

Thanks to this site, removing the air intake was a breaze!
