Review on ACDelco 216 164 Original Equipment Injection by Adam Bates

arrived quickly. Yeah, I mean after 100,000 miles they start wearing these things. You may be able to take yours apart and clean the TPS sensor, but it will still last anywhere from a month to 6 months. The bushings will wear out over time and that wet, oily PCB air will only mess up the TPS readings again. it's a losing battle. so it's better to buy a new one. and to be honest this TB costs 400 bucks if not more so the price is very reasonable. and it's easy to install. This is TB for Ecotech LE5 2.4L engine. I won't say it's unique, but it is. This is a unique TB just for us with 2.4 liter engine. it moves a SIGNIFICANT amount of air more than 2.2 Ecotech TB. I got code P2135 and checked my wiring first. Before I decided to spend money on TB as it depends on the CAR. cobalt or HHR. I've heard there can be wiring issues as well. In my situation TB was the FIX and it worked like a CHAMPION! think. SPECIFIC 2.4 liter Ecotech injectors that have been installed may be faulty. it even had a TSB for a 2.4 liter engine. hence they are fairly cheap and easy to change. What I mean is that since you are already getting into TB you should replace those injectors as they can give you all sorts of weird CODES like misfires and even low catalytic performance issues. causes mega headaches trying to track down the real problem. Just think of the injectors. Multi-Port Fuel Injector ACDelco 217-2907 OE GM $36 each. It's worth it. especially if the mileage is over 100,000. Work hard on green vehicles and always use premium gasoline. CHANGE OIL FREQUENTLY! if you get misfires go for it. understand what's going on. The last thing you want is a burned exhaust valve. They are known to stick exhaust valves. Keep your engine clean. air filter. forks. COP boots/springs/resistors. MotorKote is great for oil. and some Lucas are good at oil too. CHEMTOOL B12 is great for draining gas with every oil change to keep your engine clean. If your PCB cleaning is too high, you can install CATCHCAN for PCV SYSTEM. you can google Some people install them as they can save your TB and INTAKE cleaner. There is a great HHR forum page on FB
