Is this a Fuel Problem?

I have a 95 Wrangler 4 cyl. Just the other day i was driving on the hwy and the check engine light came on. I was driving at 55 mph. About 2 minutes later the jeep felt like it was going to stall. It shuddered/studdered. I tried shifting to nuetral and gunning it, but that didnt help. I shut it off and it cranked right back up and didnt do it again. But this morning after i had already driven about 25-30 miles it did it again. Not sure what the problem is. Anyone have this problem or know how to fix it!?

Well, if you haven't changed the fuel filter in a while it might be due and its cheap and easy to do. It also sounds like your o2 sensor in the down pipe may be acting up or being tripped by the coolant temp sensor since that can mess up the engine timing creating a lean condition. I have had code 27 for a faulty fuel injector, but in your case just make sure all the connections to the injectors are secure. Hope this helps and before you do anything expensive wait for others to chime in cause I could be wrong.
