2006 Chevy HHR 2.4 LT acceleration issue 

please note this is a 2006 Chevy HHR 2.4 LT acceleration issue. there are different scenarios that you can try to get your acceleration/ performance back. echo tech engines do have an issue about carbon buildup and have performance issues and this is also related with the Chevy Cobalt and Saturn views as well. please note carburetor and throttle body cleaner can solve the pork acceleration issue. if there's a lot of carbon buildup but doesn't mean it's going to work for everybody. please change in the throttle body would probably be the best recommendation if you replace everything due to fuel injectors, coil packs, spark plugs, fuel cleaner, air filter has been changed and you tried everything else start a body would be the next cue. throttle bodies are a big problem with a lot of Chevys up to 240,000 mi or up and it can cause air and fuel ratio issues or other. me using throttle body cleaner has solved my issue doesn't mean it's a permanent fix. could be a temporary fix for me or it could be permanent
