its an seta based 2.7i with 173 dme.
for about a week now, my car had been driving nice and strong, until it hit about 4500-5000 rpm, where it feels like it would hit a rev limiter. this would only happen under load, and in neutral it would rev to 7k.
two days ago i had left home for some errands. the car ran just fine, still strong BUT still had that problem under load.
on my way home, i had noticed that the car would run poorly and erradically through any rpm range. it wouldnt rev without misfiring if it revved at all. i made it to the end of my 8th mile long driveway, where the car finally called it quits.
it will start, try to idle but missfire and sound like shit, then die. even if i keep my foot on the gas, it does me no good. it just misfires worse and barely stays alive.
things ive done:
replaced fuel pump relay
replaced fpr
replaced tps
tried another afm
checked for vac leaks
checked ign wires and plugs, both are just fine.
fuel pump is maybe a year or so old, i replaced with a new unit from bmw.
things i want to try
new cap and rotor and ign coilpack
different dme
NOTE:
i have had the battery disconnected as i was working with the fuel, but i went to reconnect it and start it, but the car didnt have anough juice to do anything but keep the lights on. and in the past couple of days, whenever i hit a tiny bump or drove over a rough road, the stereo would skip bad.
this is making me think that there is a loose ground somewhere, and its causing all of my problems.
