2005 Saturn ION misfire and it sputters
2005 Saturn ION manual 197k miles
It starts and runs in idle ..does not overheat
I can drive it in neighborhood but I can not go on road ..
i.e. can not go pass 35 mph..
I believe after 20 mph it sputters when accelerator is pressed
recently changed spark plugs and coil pack but no change
Where do you think problem is ?
Have you had it scanned? What codes are present? If you have throttle actuator codes, you can try to clean the throttle body. If that does not correct, replace throttle body.
