I have done a search on this and found this thread which kinda describes my problem...but with a 2.4L.

http://www.j-body.org/forums/read.php?f=11&i=151091&t=151091#151091

I have a 98 sunfire with the 2200 engine. It has 139k miles on it. I bought it in '08 with 114k. Since I have owned it I have changed the plugs and wires (AC Delco plugs, NAPA wires), timing chain, fuel filter twice, intake manifold gasket, trans flush and fill (NAPA trans fluid, and a container of Lucas trans additive), radiator flush, and oil changes every 3k without fail. The car runs like it has only 40k miles on it, and quiet as hell for a car with 139k miles. My only issue is that if I start my car after it sits for awhile, and go to drive it without letting it warm up for a couple minutes. Put it into gear, and press the gas, the car sputters and bucks, and sometimes stalls completely (just like the car in the thread I found). After that the car runs fine. Any ideas???
I originally posted this in the "maintanence" forum, but didn't get any responses...I figured more people went to this forum. Thanks in advance.

Are you getting any codes? How are your o2 sensors?

I had the same problem with my 97 z with the 2.4l i found it was the egr system so i deleted the egr and programmed the ecu with a 99 program. have not had a problem ever since. i will see if i can find any fixes for it is a 2200 right?

File In Section: 6E - Engine Fuel & Emission

Bulletin No.: 77-65-25A

Date: March, 1998

Subject:
Hesitation, Sag, or Engine Stall During Cold Driveaway Maneuver (Reprogram PCM)

Models:
1998 Chevrolet Cavalier
1998 Pontiac Sunfire
with 2.2L Engine (VIN 4 - RPO LN2) and Automatic Transmission (MD9, MN4)







Vehicles Involved:
Involved are Certain 1998 J-Car Models Equipped with the 2.2L (RPO LN2) VIN Engine Code 4 Engine, that Fall within the VIN Breakpoints:

This bulletin is being revised to update calibration information. Please discard Corporate Bulletin Number 77-5-25 (Section 6E - Engine Fuel & Emission).

Condition

Some vehicles may exhibit a hesitation, engine sag, or an engine stall during light acceleration (30 percent throttle or less) when the engine is cold. This condition may be more noticeable when the ambient temperature is less than 10°C (50°F).

Cause

Certain fuels in combination with variations in manufacturing may allow some cars to run leaner under certain conditions.

Correction

Reprogram the PCM with the revised calibration that takes into account the above conditions. These calibrations are available on 1997 CD-ROM # 19 and later versions.







Calibration Numbers

Use the correct calibration from the list as shown.

Warranty Information

For vehicles repaired under warranty, use:

Labor Operation Description Labor Time

J6355 Reprogram PCM 0.4 hr

J6352 Reprogram PCM 0.4 hr
(off car)
i found the possible problem have your ecu updated with the new software.

It is not throwing any codes, and I haven't checked the O2 sensors but I could do that next. About the PCM reprogram...should I just take it to a dealership or can any mechanic shop do something like that? Oh and thanks a lot guys for the help.
