So! car used to not be able to start and i found out battery was fried got it replaced and now when I start the car it rises to about 200-300rpm's then shuts off again. I tried doing the manual TBA but so far nothing changed.. Any help would be greatly appreciated.

 

Note: The RPM's usually run around 500 when i can keep it going. It feels fine when i first start rolling but as soon as the car hits around 1500 RPM's the entire car jerk's forward and feels as if it's misfiring, when i start it up i often get a bad smile of gas. Any help would be greatly appreciated!

Thanks,

Did you check for gas leaks? Gas lines? Fuel injectors?

 

Audi newb here! not sure how to check the fuel injectors and doesn't appear to have a gas leak

 

was the car sitting? is the gas old? Have you checked to see if any of your intake tubing has come undone?

 

that reminds me of my old 240sx when the MAF sensor went out... but as im also fairly new to audi im not gonna say thats what it is... but it sure seems like it to me lol

 

the car has been sitting for almost 2 months!

 

did u have stabil in the car? fuel could have gummed up and maybe the injectors are fouled or spark plugs or all the above lol

 

Sometimes Throttle body adjustments just dont work. I've tried them numerous times on my 98 2.8 A4 that had been sitting with a dead battery for a few months and it still didn't work. If you have an ebay vag-com cable you can see if it worked. you just have to scan the engine for codes while its running, and go to measure blocks section 003 and it will tell you the TB position in degrees. If it is 0 degrees even when you give it gas, you have an issue with your TB. I'd start by scanning it for codes, and checking the TB position.

 

what is stabil? haha and i don't have a vag com i was trying to find someone to borrow one from as they are quite expensive.

EDIT: I also replaced the spark plugs and coilpacks back in august too
