I was wondering if anybody could help me out? I just bought a 98 dodge stratus 6cyl. When I punch on the gas really fast it will sputter and will not go! If I press on the accelerator slowly if will go just fine! Is there anything I could replace or do to make it run better?

Thanks,
Jesse James.

 

Welcome to DF
Check for stored codes, if none. Try cleanning the throttle body.

 

Last weekend i took it in to get it diagnosed. One of the bolts broke off on the intake manifold and it needed to be replaced, and need a new gasket. Air maybe coming in threw the hole? Also to replace spark plus, and replace throttle body sensor and it should be good! I replaced all that myself because they wanted $600 to do it. I also cleaned out throttle body, and it is still bogging & when I excellerate. Any suggestions?

 

Could be EGR valve or an o2 sensor. But these are only guess without seeing the car.

 

I replaced the EGR valve checked the fuel pressure, cleaned the throttle body replaced throttle body sensor, checked the wires coil for spark. I did a compression test on all 6 and they came out pretty even I came up with 35-40psi on all six the engine was semi warm, and then I put some oil in and came up with 50-55psi. So when I push the gas peddle too fast it still bogs and does not excellerate. I am running out of ideas with no codes! I am starting to think the timing is off but not sure how to check? Any suggestions?

 

Did you try replacing fuel filter?
