Sluggish As All Hell

[chaddy1984]

Ok i took my z down the road the other day it is sluggish as hell there is no way this thing is running on all cylinders so my first step is going to get wires, plugs, dist cap and rotor button if the problem still persists what should i do next???

Before you start just throwing money at the problem, why don't you try to diagnose it?

1. Has the car been sitting long?

2. How were you driving when the car felt sluggish? Were you accelerating briskly, slowly?

3. Does the car rev when it isn't under load? (Sit in place and hit the gas.)

4. What do the plugs look like? What plugs are you running? What is the gap?

5. How do your distributor cap and rotor look? Are there signs of wear?

6. Are your plug wires pliable?

7. When was the last time you changed your fuel filter?

Have you finished going through everything in your other thread? I would be willing to bet that your acceleration issues are directly related to the smoke...

Yep your right.

Mine does the same thing and has the same engine troubles and

also down #4 cylinder,

about 1/3rd the way down on the accelerator yields no more acceleration.

The speed just increases at steady rate from there, not sluggish but not racey either.

Well enough to get along in traffic and left by a Granny Mobile :eek: :hurt:

I can floor it and still no change in speed increase.

well it does need a tune up no doubt...so i wouldnt consider it wasten my money im just eliminating possibilities before i go and spend a bunch on a head job for the z and yes the car will idle high at a stop light or sign then i have to punch the gas to get it to idle down...

i was told the timing may be off as well...
