a quick question since u mentioned it......what all do they check witha tune-up? the air/fuel ratio and stuff like that? all ur error codes,whats causing them? I need one but im not sure who to go to andwhat i would need......this question would prollybe better in the tech section....

 

not really sure what they check in a tune up. This is the first one Ive ever been involved with since this is my first car. I found out what my issue was why my 3rd cylinder was misfiring, it was a spark plug issue. So if ur going to get a tune up, I guess theyre gonna check ur spark plugs at least. That's all I really know. Sry I cant be more help to you

 

So I went and had my Stang put in the shop. Turns out everything I had thought or heard it might me, none of it was. Turns out there was a problem with my ignition coil and I needed new spark plugs. However, turns out there is other things wrong with it that the dealership didn't fix that needed fixed. 1.) Need new brake pads (rear ones have about 20% left in them), 2.) I need new struts in the front (being new to this world of mechanical stuff, I hadn't heard of them until now), 3.) There's something wrong with the suspension in the rear wheels. A friend said he could do all these things for me as a favor because he's done all of these repairs and more becasue he works on cars and trucks with his dad. Now, I know not a lot of people will care about this next problem I ran into, but I think I should share because I need some advice after it. Anyway, about a week ago, went to school for a big basketball game. I guess I took a parking spot that someone was waiting for. So the game ends and I'm about to go out with some friends and I go out to my car, and I discover someone let the air out of my back two tires. I think I know who it was, and I guess taking a spot they thought they had was worth taking the air out my tires. Another friend who works on cars went to his house and got his air compressor and filled up my tires again. Here's where I need the advice. I was wondering what the best psi would be for the tires on a Mustang? The kids let the air out my front left tire, but not all of it, probably to cause problems in the future. Anyway, the friend that helped me said the psi in my front left tire was like 12 or 13. Anyway, just wondering about what kind or psi I should have in my tires.

 

15 i think...im not really sure,yeah i need to replace my plugs too,got a cylinder misfire code the other day [:@]
