Car is fine upon start up and for the first ten mins or so......After that, hesitation bogging until 3,000 rpm....

So, I'm guessing primary fuel pump..50,000 miles I have and I'm guessing original pumps....

Bought my car around to my mechanic and make a long story short I have the fuel pumps out of the car.....Weird thing is today I'm driving back from there ( short distance)
,service engine light comes on but now car is running fine.....Get home and I parked it....Ten mins later I get into car and I figured I would just bring it back and get it scanned

Got a few blocks ( no service engine on light) and car started to do the original symptoms-- bogging until 3,000 rpm...

Just took it home parked it and removed the fuel pumps.....

Wonder why light came on but ran fine with the service engine light on....

Will keep everyone posted after I put the new fuel pumps in...

Peace...
