Tip & How-To about Chevrolet Beretta
If your car experiences erratic idle, you should first clean the IAC (idle air control), using throttle body cleaning... spray sensor and also check the hoses going to the MAF (mass air flow sensor), the hose might be cracked and brittle. Another tip: if your IAC was extremely dirty, then take some carb spray and clean the throttle body and plates thoughly. And if you truely want a great running car, and improved gas mileage, pull plugs wires one at a time and wipe down the wires and clean the coil towers also, take a wire brush and knock off the crime. I use a carb spary and get all that carbon tracking off the wires, and then replaced all plugs (with only standard heat range), for your vehicle. if you purchase those fancy iridiums and you try and gap them the expensive platinum tip will usually break and cannot be used ...just trash them and buy another $16 dollar plug if you want but i find that the $4 plugs work just as well but you just have to change them more often ...and if no gasket only tighten 1/16 of an inch turn and you should never have a problem geting them out next time.
