Stumbling '98

I have a '98 Expy with 40K miles. It recently sarted stumbling or missing under light acceleration. It does not occurr under moderate or heavy acceleration. Changed the fuel filter and air filter which fixed it for about 500 miles. Now it's doing it again.

No check engine light and no error codes. Any thoughts?

TIA

I have been experiencing the same for the past 10,000 miles. I am interested too in the cause for this. Thanks for any responses to this.

I have a 98 Expy with 75,000 miles and I had the same problem at about 72,000 miles. I had the plugs, air filter, and fuel filter changed, and the problem went away until last week when it returned. I'd be very interested in finding out if anyone's found the solution to this.

[updated:LAST EDITED ON 05-Aug-02 AT 12:15 PM (EST)]Some of us are having trouble that is somewhat like you are having. The posting below yours on this website may be helpful. It's subject line is: intermit. rough idle, check engine w/ P0171 & P0174 codes. This may not be your problem, but it's worth a look. Good luck.
