it seems like my 1991 jeep yj is not getting the right power it should and it seems like it is flooding it's self the fuel pump in good, fuel filter, converter is good, got good fuel pressure in the lines none are leaking sensers are changed like the map, temp, and throttle body, and oxygen. the only only thing i can think of is the timing but she idles good so i don't think that would be the problem...and ideas what to check/look for before i strip apart the engine?

pull hair

Take a minute and breathe. That's one of the longest sentences I've ever seen.

I'm having the same problem, but my idles pretty low. I know the previous owner advanced the timing and I haven't touched it since. Could that be my problem?

Edit 4/25- the timing chain is advanced, the actual timing should be fine.

When were the sensors changed? Last week or 35,000 miles ago?
Make sure th O2 sensor is pluged in all the way. I have seen this several times before.

What do your sparkplugs look like? Are they fouling? Are you blowing any smoke out the exhaust? If so, what color is the smoke?
