Question Car is jerky, what is wrong

Alright so my stock 99rs with 80k, started jerking a bit whenever I gave it gas. A blinking CEL came on and when I had the car in the Subaru dealership earlier they said that the drive belt would need to be replaced sometime in the future but not immediately.

So does the drive belt have anything to do with this? The dealership was a bit foggy when they explained things and I want to get to the bottom of this. For some reason the dealership said replacing the drive belt would cost like 400 bucks. Also, the alternator and power steering belt is cracked

Not the Drive Belt..

the Timing belt, and yes with your mileage it should be changed soon, as well as the crank oil seal and water pump at the same time, (water pump is driven off the timing belt, and the crank oil seals always leak, might as well change them while they are in there)

your drive belts/accessory belts, are you alternator and power steering belt. They sholdnt charge you any extra labor to put them on, just the parts price because they have to take them off when they do the timing belt.

anyhooo

your problem sounds like bad spark plug wires, wich would be a safe bet if you have never changed them. Pretty common with scoobys and high mileage.

Should change the plugs to when you change the wires.

Ignition wires, certainly, but it could also be water in the gas if it was a sudden change.

Well, the timing belt is good bet. My car is doing the same thing, oddly I threw a CEL today, EXACTLY 1 year to the day from having this done last year. What gives??

There is no logical reason to have the timing belt go bad and then cause the CEL (misfire in 3) after only 15,000 miles. This is now the THIRD time that this has happened to my 98 GT wagon. My car is cursed. I hope that it can be cured this time. Actually, I am REALLY hoping that my mechanic will back his work since there is no reason for this to happen, at all.

If anyone knows something that can explain this please tell.

Oh, and sorry for the hi-jack, but it might help you too.

I dont see how a timing belt would cause the car to be jerky at times. I had one break on me with my motor swap. The car acted fine up until the time when it broke.

I thought that the 99 RS is SOHC? If this is the case a timing belt change should not be 400 bucks. I had mine done on my SOHC ej22T and it was only 250 bucks.

Anyone think it is a MAF issue?

Well if you're going to get it done at least don't give your money to a subaru dealer and save yourself a ton by finding a good independant mechanic who works on or specializes in subarus.

The wires "looking" good isn't enough. Wires can look good with 200,000 miles on them - just clean them. With 80,000 miles and 5 years on the car I can assure you that the wires are due for replacement.

I was thinking MAF. My car is doing the same thing, more or less, but only before it has had a chance to warm up. Other thought: Have you replaced the fuel filter or air filter lately? My GF bought a 95 Integra which was having bogging issues. I decided to check the air filter. Good thing I did. It was solid bugs and dirt. I don't know how any air actually made it to the TB. Crazy.

Ignition coil. I have had 2 go out on my. Same symptoms, except I never got a CEL on my '00. If you have an ohmeter, you can follow the test procedure in the manual.

i have this issue with my MY01, but i only get the shacking/hesitation when i'm at higher RPM's, mostly in 2nd and 3rd. sometimes in 4th but very rare. i was thinking something to do with air flow, never thought about timing belt, but considering it's almost at 75K.....who knows. i guess it's just time for a good tune up.

any other suggestions for the higher RPM shacks?

Actually I just got a tune up and that is when the mentioned the drive belt thing. But the car doesn't jerk anymore... it just stopped. Of course I have only driven it back and forth to work a total of like 2 miles a day so I plan on taking it in when time permits.
