I've had my car in and out of the shop for several weeks and I'm really becoming very frustrated. I don't really know ANYTHING about cars, but about a month ago the car would sporadically have trouble maintaining gas flow (The RPM would teeter around 1 and then go down to 0 and shut off).
The first mechanic said that they fixed the problem by replacing the battery leads (that cost $90). The next day the car stalled on a main road and I was able to get it to a national brand car shop. They diagnosed the problem as needing a new fuel injector and pump (the diagnosis was $125) and they estimated the problem would be well over $900 to fix.
So I got the car home and debating my options (that is a lot of money to put into a fairly old car with lots of miles). I ended up taking the car back to the first mechanic and told him what the second mechanic said was wrong. He couldn't find this problem with his computer tests, but did end up replacing the fuel injector and pump (for $700).
I've had the car back for a few days now and I am STILL having struggles with starting the car and it occasionally stopping while driving (like it isn't getting gas). I am really so frustrated and upset that the problem is still acting up, especially after all the money I have spent (almost $1,000).
I would have just sold the car off instead of fixing it if I had known it was going to cause this many problems. Can anyone tell me what they think could be going on and causing the car to still stall and not start properly? I am going crazy. I don't really know the first thing about cars, but I just feel so frustrated by the problem not being fixed with all the money spent.
Update: April 17th
I am going to offer the vacuum leak as an idea to the mechanic. They ordered the mass flow sensor but it didn't fix it so luckily I wont be charged for that. Unfortunately, they said they "just don't know what's wrong with it." They have a professor of mechanics at a local tech school coming in to take a look at it. It is very discouraging news, because over 1,000$ and more than 3 weeks later and I still don't have a working car. I just have to sit and wait.
