Hits 5000 in 2nd bogs down hits 4300 in 3rd bogs down 2006 cobalt ss sc no mods any suggestions why

 

no mods thats kind of weird thats happening...maybe clogged fuel filter? Doubt it though...maybe someone else can chime in and help ya out

 

fouled spark plugs maybe? have u checked anything out yet

 

not really just started noticing slow throttle response yesterday and noticed the bogging down taking off fast yesterday.......just needed a place to start looking or if someone else had the problem before could narrow it down pretty close....spark plugs was my first place i was going to look........thanks will check it out

 

Im having the same kind of problems right now.

 

also take the throttle body out and clean it too. that sometimes has something to do with throttle response. other than that i will keep thinking but i got nothin else as of now

 

Hello fellow peterson

 

How many miles are on your car and when was the last time you changed the spark plugs? These cars can go through spark plugs pretty quick with there rich tunes and there even more rich gm stage 2 tunes lol. I recommend changing out the spark plugs first, if the problem still persists try cleaning your MAF sensor and your throttle body. If you have more then 50k miles on the car, or close to, also change your fuel filter. Since your stock, take your air filter out and hit it against your leg a few times to get all the dust out and put it back in. That is pretty much the basics to start. I recommend doing this stuff on a warmer day.

 

thx..........will try all.......spark plugs got replaced about 1 year and half ago.....car has 20000 miles on it but will check them still and air filter(not sure if that would cause bogging down) but spark plugs could and also fuel filter....thx for help guys will get back with ya let you know exactly which one it was exactly...

 

I changed my fuel filter at 18K miles , and you wouldnt believe the **** that came out of it . I only run 93 at good gas stations too. I'm changing mine at 10K from now on.

 

Ok im goin to check it out and yea i only run 93 and use shell gas

 

and may i add supercharger is making a whistle kkind of sound not the normal whine that one makes but a whistle dont sound normal

 

I had the same thing going on last week, My engine would sputter at high RPMs and would bog out and hesitate. And I was losing gas milage. I ended up replacing the spark plugs and it all went away and the car runs great and normal now. It could be four things but start off with the cheapest repair first of course

1) spark plugs are bad and need replacing
2) THe Fuel filter is bad or fuel lines are clogged somewhere
3) Coil Pack bad
4) wore case senario but highly doubt it, Your timing is off
