I know that the catylitic converter is stoped up, and its using more gas than normal, do you know why. Tom Greenleaf Ultimate Carjunky / Moderator Apr 6, 2008, 6:57 AM Post #2 of 3 (1756 views) Re: 95 corsica Sign In Ah - I thik you just answered your own question! Next is WHY is it stopped up? T brbettge User Apr 6, 2008, 10:59 AM Post #3 of 3 (1753 views) Re: 95 corsica Sign In Tom is right. the car is sluggish because the cat convertor is stopped up. The cause is because it is using more gas than normal. the reason it is using more gas than normal will take some work. the first thing i would do is look at the oxygen sensor. take it to autozone and have them pull codes. if you are lucky enough to only have an "oxygen sensor LEAN" code; you now know that your car's computer is compensating for a lean condition by increasing the fuel supply (increasing the injector pulse width). Why, now, is it lean? There could be vacuum leak(s); or there could be dirty/clogged injectors, or you could have a stopped up fuel filter, or you could have a bad oxy sensor. If you have not changed your fuelfilter do so now. Get a new cat convertor installed next. If the problem still exists look over the engine at all the small black pencil sized hoses for breaks/cracks/rubbed holes. Did not find any bad hoses? Still have fuel consumption problem? go to wally world and buy 3 bottles of chevron techron(tm) and pour all 3 bottles into your full fuel tank. This will blast any crud out of the injectors if they are not too far gone. This will take at least a full tank of fuel driving time to work if it is going to work. last, thing to do would be to replace the oxy sensor. these are the only the most obvious things that might cause the car to use too much fuel. if these "first line" repairs don't work you may be in for some diagnostic time on such things as map,tps,ecm,further vac leak searching, etc. be careful around the hot engine parts, and follow all directions on additives except the amount of techron to add to the system. 3 bottles at once is an old mechanics trick to quickly clean injectors on a car.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
