Today i took my car out, and it felt real laggy it feels like either the cars not getting enough fuel or the pistons arent getting enough spark. On my dash board where the miles apear a new message apeared saying "service insp" I got new spark plugs about 3 months ago, i changed my oil yesterday, and i only use super 93 octane gas. But yesterday i was told to put some fuel injector cleaner in my car. I drove my car yesterday and it felt normal but this morning i dont know if its the car or the hangover i have. But the car felt weird. Also about three times after i stopped a stop sign the rpm's dropped to about 300 for a second and went back to 700 which is what it normally revs up to when still. Any idea what this might be could it have been the fuel injector cleaner? Or i might need new wires?

The car feels laggy like lost of power. I also have 18 inch rims on but it never felt this weird. Even though they are slowing me down.

 

Sounds like a failing O2 sensor.

 

Agreed

 

When is the last time you replaced the Fuel Filter... My car was feeling really Lag like... till i changed that out and it got some more pep to it... give that a shot. its a lot cheaper than on O2 sensor and should be done even if it turns out to be the sensor
