Does this video sound like a misfire? I'm buying a new cas online instead of second hand just to rule out any possible problems

Ok I will try that, if that doesn't work then what my cas is shot? that's a link to the video of what the cars pounds like

Gtsboy yea I seen the prices but I might be able to rent one. It does seen a little to advanced for my inexperience, the thing is my car needs to pass safety before I can pull the motor or do anything drastic. I just need the motor to run fine for the inspection. Is it the low compression in that cylinder that's causing the misfire? The engine does have a loud tick now

I'll get that led test light tomorrow aswell

Bick033 ok I'm going into town tomorrow and I will get one, I couldn't really put much time into the car today as that's all I've been working on all week, and this is my last few days off work and I will be gone away for awhile so I had to do some work around the acreage. I put the plug up agains the breather and couldn't see a spark, but I will go buy the oscilloscope tomorrow and try it

It was 105 without oil and 140 with a cap of oil

So I did a compression test and I got values starting from the firewall back, 105/140 after a cap of oil, 130, 150, 150, 145, 140. I didn't waste time putting a cap of oil in the cylinder that's at 130, or the rest of them

Xklaba, the last compression test had shown that there was 135-140psi between all cylinders, but when I did that compression test it was really cold still I'm not sure if the cold would have effected the results by thickening the oil, bick033 I got a regular test light would that be fine? An oscilloscope is that just another word for timing light?

Ok thanks, I did a compression test awhile ago and numbers were good, but noticed the previous owner over filled the motor with oil and I drained some of it out and did a test again today and numbers did not look too good, I called it a day and I'm going to do another test tomorrow and see what that shows, I will do a compression test before and after I drop a cap of oil in the cylinder.

My you saying swop for known working one? It's not that easy to get gtr parts here in canada, people are dic#s about skylines and hrs cars here do not much available

How do I test the cas?

I swopped over injectors, no difference just the one cylinder has no spark, can I hard wire the coil pack with a relay and try that?

I swopped over injectors, no difference just the one cylinder has no spark, can I hard wire the coil pack with a relay and try that?

Could it not be the timing thrown out slightly and that's making it spark to late and not causing that cylinder to fire?

I thought about that, but there is fuel going to that cylinder, because after I start the car and I pull out the plug, the plugs wet.

Yes xklaba I've swapped the ignitor with a known workings ignitor still no luck, the car boosts great now and wants to rev up but the mis is just to bad. It's also a little harder to start, won't start without a little gas, I've stripped my wiring loom and there was a bunch of joins in it, ok not sure if they were supposed to be there but doesn't look like a factory harness would be spliced joined and taped.

Help anyone?

so my car seemed to run good for a few days, i was not driving the car because of the snow and im getting it inspected, but now the mis fire is gone really bad, i found a boost leak between the intake manifold and intercooler, theres spark at all the other coils except the coilpack closest to the fire wall, i need help please!

Thanks. I just don't want to order a set and they don't fit. That's another waste of money

Help anyone?

That's what I was thinking, I'm pulling the turbos off within the next few days, it's pretty damn cold here so I'm just putting in an hour after work.

It can Mainly hear it at idol, car doesn't run fine, I'm thinking the turbos are bad. Could this be a sign that the exhaust wheel is about to go?

It has a test piece so no cat

I have a 1991 gtr and there's like a lumpy noise coming from the muffler sounds as if there's a train running over some tracks in my exhaust, anyone had this happen to their gtr before?

Shit that's not good nammy, I'm afraid that might happen, what signs did you see when your turbo blew?
