“Ecotec Gen I was re–engineered to be smoother and more efficient than its predecessor. Featuring an dual in–block balance shafts, power–steering pump, water–pump housing, and removable oil filter housing. This engine replaced the Quad–4 and GM 122 in North America and first appeared. GM offers an official kit which can be converted into 2.2 supercharged versions using modified ECM software. Model L42 is an CNG version of the Ecotec 2.2, producing 129 hp and 129 ft⋅lb. This LSJ was listed as one of Ward's 10 Best Engines in 2006! Sealed transmissions elude fluid access to function like regular transmission systems without requiring fluid changes for maintenance. A sealed transmission has fill and inspection plugs, with the inspection plug removing excess fluid and the fill plug adding fluid. Nobody told me during my tenure in ‘shop class!’ Knorr’s Automotive wants $55Ø to fix an exhaust leak, which is their disastrous mishandling. This situation is only going to get marked by more confusion & errors. Vehicle fires are rare and small leaks in fuel tanks or lines can ignite, in defective vehicles during crashes.”

“Korr’s Automotive wants $55Ø to repair our exhaust leak. Fuel lines are too close to engine, which can cause death or injury upon impact. You’re welcome for [XXXXXX] upon request! Driver seat is out of commission on power.”

“Body, Brakes, and Electrical concern me. My family owned a 1999 same model vehicle, and the brakes failed us in an accident from its’ left driver seal being punctured. Here is what’s going on with the 2003 aside from the latter mentioned. Exhaust from manifold to catalytic converter followed by muffler rusted out by 175,ØØØ miles and now broke apart. Frame and rocker panels are rusted out before 175,ØØØ miles and broke apart by rear wheels on both sides. Electrical concerns caused me to quit my job on March 11, 2022 when the wipers quit working and nearly caused an accident by Chartiers Cemetery in a thunderstorm storm two days before. Front end vibration is felt in floor boards and steering wheel when brakes are applied at high speeds, usually between 45–75 as regulated by federal government. Disc brakes gradually replaced drum brakes from between 1960—1980. That practicality is debunked on these cars they didn’t utilise disc brakes on all both axles, which is my preference anyways for being mechanically–inclined. Koor’s confirmed our exhaust leak in Carnegie Pennsylvania and wants $5ØØ+ to replace the exhaust. Tireman Auto Service in Toledo Ohio confirmed the…”
