Default toyota engine problem, need help.

I know off topic is for non technical topics, but I don't know where else to put this where it will get viewed quickly. My friends 2000 Toyota Corolla is having problems and she is stressing. The car only has about 40K on it, and the warranty just expired. I am just learning about cars with my WRX, so I wasn't totally able to help. Her engine/car shudders at idle and continues until up to speed, and doesn't accelerate as it used to. Her Uncle thought maybe it was the spark plugs, so he changed them. That didn't help, so she took it in to the dealer. They told her that it was probably the spark plugs, and when she told them that they were replaced, they said she needed to use factory plugs and that her uncle put the wrong plugs in. They gave her the run around for a while with various calls. Next they told her that her fuel delivery system in each cylinder is broken. The new part has to be ordered and it will cost $1000. I looked up possible causes and spark plugs, spark plug wires, and fuel system problems came up. Just wondering if anyone has any feedback from what I have described above. I have learned a lot of technical information on this site, so this is the first place I thought of to ask. Thanks in advance.

I think the big problems are as follow:

1) It's a corrola (and I'm a Toyota Fan so...don't think I hate Toyotas)
2) A chick drives it every day
3) IT's a corrola

Before you spend big bucks at the dealer, I would do the following in this order:
- Check to make sure the new plugs are really the right ones (don't have to be factory-spec, just the right temp, gap, etc). Make sure they are firmly seated and the plug wires firmly attached in the correct order.
- Then check carefully for loose vacuum hoses (basically check every hose in the engine compartment).
- If the plugs are OK and no loose hoses, run some fuel system cleaner/water remover through it and fill it with fresh gas. Also change the fuel filter.
- If that does not work, change the plug wires.

That's all I can think of for now.

How would engine mounts affect acceleration?

Definitely get the code read; that should identify the problem.

It wouldn't affect it too much, but if you have a broken engine mount you're engine sways alot and you would lose torque to the drivetrain.

The engine mounts are probably not it, as I drove my old Accord for thousands of miles with toasty engine mounts. All that would account for would be a vibrating steering wheel at idle, I think. Power shouldn't be affected too much.

<what everybody else said>
40K miles, look at those plugs again. If they're not the right temp/gap, that's probably it. If they are, check to see that all the hoses are hooked up tight and right. If they are, get that code read and go from there. It might be something as simple as a gummed up o2 sensor forcing the car to run rough. Fuel system cleaner might help, too.

Unfortunately, she is in Seattle, so I can't get my hands on the car. She heard back from the dealer and they said one of her fuel injectors is broken. They recommend replacing all four, which is $172 per cylinder, and ~$250 labor. Thanks for all the input, again, it was very helpful.

If its 1 fuel injector, why do all 4? I would just do that 1 and see what happens.

Also, fuel injectors should not go bad after only 40 k (The ones in my 95 legacy have never even been cleaned in 170 k)

Tell her to take it to autozone to have the codes read. If she flirts a little, maybe one of the guys there can fix it for her.

That depends on your refill policy and the quality of gas used.

Let it run too low and you risk contaminants getting thru. Use cheapass gas and you risk more contaminants and other things associated with cheap gas.

My sister-in-law, who is notorious for using Arco, which btw is crap, and always runs it to the bottom. Her injectors on her 99 Civic clogged after 2-3 years of usage. The techs told her to stop using Arco. Funny.

When they're replacing the fuel injectors, have them saw the ends off to make them giant 740cc injectors. That should really help her when she starts to put down wheel-smoking torque later.

I usually buy el-cheapo no-name gas and fill at 1/4 tank. I do agree about running too low; I never do that.

She needs a new high flow fuel pump too then!
