I have a 1999 Chevy Metro with the 1.3 liter 4 cylinder. The catalytic converter was stopped up when I bought it. So I cut the catalytic converter off of it and put a new exhaust system on there. I also replaced the air filter system with a cool air intake. I ran it for about 30 miles before it started backfiring pretty bad on me. Within a day or so, and started popping and sputtering as I drove down the road. And I had a severe loss of power and a Severe drop in gas mileage. I had to keep my foot on the gas when sitting at a stop to keep it from dying. And now I can't get it to start. I have replaced the spark plugs, which were very badly fouled. I've recharged the battery. It still won't start. I should probably also note that it was not only backfiring out of the tailpipe, but it was also backfiring in the air intake as well. And now the underside of the hood of my car is nicely coated with a film of oil and gas.JA: Where exactly do you think the noise is coming from? And how long has this been going on?Customer: like I said it is backfiring in the exhaust system and also underneath the hood, I assume in the air intake.JA: Are you fixing your Metro yourself? What have you tried so far?Customer: Yes I have been attempting to fix it myself. I bought it kind of is a project. I knew that the catalytic converter was bad on it when I bought it. And it was missing a muffler. So it was very loud, and if I ran it very long it would start to overheat from lack of air flow because of the catalytic converter. So I cut the catalytic converter off of there. And actually ran it for a day without a muffler. I had also replace the air filter system with a cold air intake and ran it with the cold air intake and no muffler for a day. It would backfire then if I happen to let off the gas and decelerate very quickly, but otherwise ran fairly smooth until the end of the day. By the time I had returned home that evening it was popping and sputtering pretty bad.JA: Anything else you want the mechanic to know before I connect you?Customer: That's what I figured that it had too much air flow, and was running extremely lean because of the lack of Muffler. So I put a muffler on it which definitely quieted it down but it did not fix the sputtering problem. The sputtering continue to get worse, and now it won't start.

well it surges forward, shuts off when coming to a stop or driving down the road, but this shutting off happens after the surging forward, there is a burning rubber smell and the service engine light comes onJA: Do you have the trouble code? Do you have a code reader or scan tool?Customer: no we are not mechanics but we did take it to a mechanic and he told us it was repaired but it is worse now than before we took it to his business. He replaced and mapped sensor and charges $320.00, so I though I would do some research online before taking more action.JA: I'll pass this info along to the Chevy mechanic so that he can get you a quick fix. What is the make/model/year of your car?Customer: This is a 1993 Chevy S-10 Blazer.JA: Are you fixing your vehicle yourself? What have you tried so far?Customer: We are not fixing it ourselves. We took it to a mechanic who replaced and mapped sensor and charged us $320.00. Now the vehicle runs worse than it did before.JA: Anything else you want the mechanic to know before I connect you?Customer: Could this have anything to do with the catalytic converter?
