OKAY. This is my first post although referenced this site many times for advice on how to fix my car. I will start with a bit of background, I have loved sn95 since I was a kid, I am a 90s baby, so these were the cars that were new and shiny when I was a kid, and my whole family has always been ford drivers. So fast-forward to now. I am 23 years old and have finally saved enough money to buy a secondary vehicle other then my work van and I got gitty and bought a wrecked 1996 Mustang gt with 98000 miles on it. I'm familiar with wrecks have bought and rebuilt several. Parts replacing is easy, this car has a seperate issue. Its a mechanical NIGHTMARE. All I do is work on this darn thing and I can't seem to get a step ahead. Drive it home first day that I own it. Stop it in the drive way, come out the next morning, there is a ****ing quart of oil on the ground. The prior owner is an idiot, somehow cracked the valve cover and then just smeared silicone all over it to fix it. the "CAI" was pvc with couplers on it. This is just a couple examples so you can understand this car. So, I am fighting with this car because it is running INSANELY rich. To the point it isn't tolerable to be in the car. These are the things that I know are working against me and I will also list the codes that it is throwing so maybe someone has had similar experience. The car has an offroad H pipe, and two flowmasters off of them with no tail pipes. the mufflers also are just rotted out one has a hole the size of your fist in it. These are the codes its throwing p1443 Evaporative emmison purge valve malfunction p0131 Oxygen sensor circuit low voltage bank 1 sensor 1 p0135 Oxygen sensor heater bank 1 Sensor 1 P0136 Oxygen sensor circuit bank 1 sensor 2 (see p2270, 2271) p0141 Oxygen sensor heater circuit bank 1 sensor 2 p1130 Lack of heated oxygen sensor (bank 1 sensor 1) switch, Adapt fuel at limit p1131 Lack of heated oxygen sensor (bank 1 sensor 1) Switch, indicates lean p1132 Lack of heated oxygen sensor (bank 1 sensor 1) switch, indicates rich P0172 Bank 1 System to lean (non-mil) P0171 Bank 1 System to rich(non-mil) Any advice I'm open ears, because at this point I'm about ready to count my losses and TRY to get my money back and find another sn95 lol.
