Hello
My car starts and idles fine. It'll run fine until about 1500 rpms then starts to stumble and eventually cut off unless I let it get below 1500rpms. This just started after stopping for a morning cup of coffee. All my car buddies says fuel filter or pump. Any test I can run that will validate this? Also is it difficult to replacing fuel filter and pump? My abilities run upto basic brake jobs.
thanks
mike

Sounds like a fuel pump, I filter wont act that way. Ive done a few of them and there not that bad to do. Youll need a pressure gauge to verifey but I bet its the pump. If you remove the back seat there is an acsess hole that needs to be heated up with a hair dryer to get the cover off. From there its pretty basic. Youll need a large channel locks to turn off top on sender unit. Good luck
