I have '96 Accord with a 2.2 engine. The engine intermitted hesitates and stalls during acceleration or a constant speed. Never while idling. It only does this about 20% of the time but it is very dangerous to drive like this. You never know when you pull out into traffic what is going to happen. I changed the fuel filter and tested the fuel pressure. I took it to the Honda dealer and they said they could not duplicate the problem but recommended they change the main fuel relay for $260. I picked one up for $60 at NAPA and changed it myself (very easy) but this didn't help. I tested all the spark plug cables and changed the spark plugs. I feel very frustrated at this point not knowing what to check next. Any ideas would be appreciated.
Thanks.

 

I also tested the egr valve today by disconnecting the vacuum hose.

 

DISTRUBUTER

 

I took the distributor off and inspected it. I didn't see any cracks or corrosion. Any other way of testing it?
I dropped the gas tank today and inspected it. No trash or water.
Never had a problem like this that can't be diagnosed.
