Computer problems???

Hi, my 94 C 280 randomly will make a hicup noise and then start missing a cylinder, they car shakes alot due to this. When i turn the car off and then back on everything works fine. Can anyone tell me what is causing this or possibly how to fix it???? Thanks!

Yell BOOO maybe the hicups will go away :D. I would find a local shop and have them hook it up to a scanner and search for codes.

RE: Computer problems???

codes come up P0002- undocumented
34- O2
35- O2
37-EGR

i would assume the O2 and Egr are set off because there is a mix of bad vapors that are setting them off for the one cylinder not firing......
