Recently my 95 Z hasnt been running right....the idle seems real low and smells rich (stong fuel smell) also seems to be lacking on roll-on power and overall power. car still acts wierd after somewhat long drives on the interstate and bogs WAAAAY down......HEEEEEELP!

 

need more info: miles, m6/auto, mods, etc.....

 

95....auto, 61K miles, MSD 6A ignition, k&n filter, headers, no cats, flowmaster 40 series......thats all i know of

 

Is the service engine light on?

 

nope

 

First thing to check when running rich is the oil contaminated with fuel. The very next thing to check is the air filter for dirt, over oiled or water soaked. Then check for dead cylinder(s). Change the oil if it does have fuel in it. If you have a dead cylinder, you know it has to be either spark or compression because it's rich. You can rule out fuel, but odds are it's spark related.

If you don't have any of those problems, it's time to check some things visually. Start easy and work your way hard. Pull the entire intake elbow off and see if there are any cloggs, voids or tears. You'll be amazed how many stock intake elbows you'll see rolled under at the throttle body. While you're there, check the MAF for contamination from an over oiled K&N and spray with break cleaner(while it's off and completely cold) if it needs cleaning.

 

cool i'll do that stuff as soon as i get a chance

 

car seems to have a "shimmy" while just cuising at about 45ish.....need my 60/65K service done and a tranny flush....think that'll help the overall problem?
