Miss like it hits a brick wall at 4000 RPM

is it a hard miss or just a hesitation kinda lack of power

**White93z34** · 05-29-2005, 09:26 PM

its just as if you were to take a z34 with the factory rev limiters and mash the gas in park till it bounces off the 3k rev limiter.

Exactly what he says. I couldn't describe it any better.

well what did the fuel pressure do when you drove it?

Well, attempted to hook it up, but the guage doesn't want to reach far enough to be able to see what its reading with the hood closed. In park, it sets a little under 40.

Ended up taking out the hood vent and propping it up out of that. At idle, sits right around 38, driving is about 40-ish, at 4000 rpm, it is right about 45 (this guage is kinda crappy, but it works). When it bounces back and forth, it bounces from 42-45.

Sounds like the fuel pressure is just fine.

**4spdz34** · 05-30-2005, 09:31 PM

ya thats what i expected, i would start swapping some ignition stuff, or start ohming out teh wires and coils

**slick** · 05-30-2005, 09:44 PM

What should the coils ohm out at? Same with the wires?

**slick** · 05-31-2005, 01:03 PM

I pulled the plugs off of each coil pack, and put my tester up to them. They seem to all have fine resistance. How do I go about checking the wires?

I'm doubting its ignition. It soulds like the car thinks its in a different gear. But you said you replaced the PRNDL switch. Have you tried the Park Neutral Saftey Switch?

Not yet, mainly because I have not recieved a definate answer on where that is located. I keep wanting to say it's underneath the shifter maybe?

EDIT- After looking at my Haynes Manual, the park Neutral switch is what I have replaced. So, where is the PRNDL switch at then?

**JoroCorona** · 05-31-2005, 01:59 PM

Well, your using the same manual as I am... So if you don't know neither do it.

**slick** · 05-31-2005, 03:13 PM

I should have a VSS coming in a few days, and Tony(5speedz34) is gonna bring me a set of coils and ICM, so I'll give all that a shot too.

**5speedz34** · 06-01-2005, 01:47 PM

Ok, cool I'll go look in my garage tonight for them.
