PostSubject: Car running like crap need help   Fri Apr 22, 2011 4:14 pm

Okay So I bought this car about two months ago and I've had a lot of problems so far. Car was running okay with some crappy ebay wires but one broke so i had to get new ones from an autoparts store. Then is ran even worse. Replaced the spark plugs, cap, rotor, fuel filter, new gas, also siwthced out the mafs, and injectors but it still ran like crap. Took the wires back and got the same ebay wires. The car idles under 1k and kind of moves down and back up and it seems like it's missing still. Not nearly as bad as it was. Then today I took a video and the idle was oaky but the the car just stops reving after 3 grand (almost like a 2 step) This thing isn't running right at all. I have no idea how to fix it so i was wondering where I should take it. I live by west bend but I can have the car trailered. I need someone who really knows what they are doing. I was wondering if there are any shops that anyone knows about that specialize in 240's or nissans besides a delaership. I Don't want to pay two grand to get this thing running because thats more than I bought the car for. Also the car is running very rich and needs a tune very badly so if I could kill tow birds with one stone that would be great. Thanks in advance guys

Rough idle, running rich, low power after 3000 rpm,sounds like a vacuum leak. Remember the car is old and rubber hose don't last forever especially after many heating and cooling cycles. It takes time, but inspect all of the lines very thoroughly.

Yep, check the basics. Vacuum leaks, timing, and fuel.

Okay so the maf harness was loose so now it will go past 3 grand aka no unwanted two step. The idle is okay doesn't bounce around too much but it still seems like it's kind of missing
