The problem:
The stomp test code I am getting is 1222. Haven't found a shop that has a code-reader on hand.wafflesThe car will 'studder' when not in gear going from idle to full throttle, then smooths out after ~3k. When driving, the car often bucks/ feels like a misfire when driving under 3k. It will drive smooth when driving it lightly/ at below maybe half throttle, but if you are hard on the trottle in any gear it will often buck/ seems to be low on power (when less than about 3k). Even after about 3k, the car seems slightly low on power. I didn't recognize the problem for a while, as drive relatively slow/calm to and from work.
I have replaced a few things since none of them have been done in the last 6+years. Replacements include: vac. lines, o2 sensor, fuel filter, IVC, fuel pressure regulator, spark plugs, wires, intake and valve cover gaskets. Opened the AFM to confirm movement of dial when rpms are raised/ lowered, compression is about 150 throughout. I personally can't find any leaks (did a ghetto smoke test)wafflesbut a professional test hasn't been done.waffles
thank you for your time.
It was the fuel pump.
