Hi guys how are you doing today.I got a question for you and hopefully you could help.My 240 was running fine like a week ago and all the sudden my engine started shaking real bad.I took it to a mechanic and he did the diagnostic on it and said that im not getting enough fuel from my injectors but he wasnt 100% sure about it.Will that make my engine shake or is it some thing else.I was about to order all the easy bolt ons including a 50-75 shot of NOS but now i got to wait and find the problem.Oh and when i turn the car on and drive it it runs perfect until i let go of the gas.I tought it was a vacum leak but it wanst.I whant to get my car running again really bad cuz my friend got his honda crx with a b16a running again and now his talking sh**.His mad cuz i smoked him long time ago with my car bieng stock and his with the swap:ylsuper . But if anybody could :help me i would really apreciate it thnx a bunch;)

And allso does anybody know what a 1989 240sx se hatcback runs at the 1/4 mile with just a injen intake?

I ran 16.366 at 88.261 mph just whant to see if my car improved alittle.Oh and sorry if to long and if i missed pelled some words not good at writing

injectors, fuel filter, fuel pump, spark plugs, plug wires, distributor, improper compresseion.Start with the cheap thing (fuel filter) and go from there until you find the problem.

the only simptoms it has is that the engine shakes when in nuetrol and it idles very low and i all ready put new spark plugs,wires,distributer,and new fuel filter. And the mechanic I took it to said that my fuel pump is ok. But i think he really doesn't know much about nissan he mostly works on hondas and hes the only one that came cheap and knows about import but thats what he says.

Mine shakes, sometimes it would even die... that is after I put about 50 shots of dry NOS and froze up my MAFS, luckily a buddy of mine did threw in a SR so I had a extra MAFS lay'n around. I double checked all my vacuum lines but all seems fine and I drove it like that for a while. Sometimes it would even die. I thought my motor is F***ed up but I found out today that it was just a tubing that goes into the intake. If you already changed all those things, I'd probably just find some time and rip out what I can from the car and reassemble including all the simple items such as intake, plugs, wires, etc, especially vacuum lines.
