slow acceleration? Options

[momentai99]

hey guys, i'm new here and picked up a white gt a couple months ago. (94 with minor alterations), but it was 500 bucks so hey can't lose right?
well I knew the clutch slipped a bit but i'm not sure if this is the clutch or not so i'm here for your wisdom. Btw this car will be converted to a gt four next year.

so back on topic, the car is suddenly having almost no power on hills (i live near pittsburgh in the mountains), it's a 5 speed by the way. Well a friend suggested it could be my cat but it FINALLY threw a cel (its gotten pretty undrivable). the cel was for the egr system, so again to the cats. So we unplugged the hose from the valve and thinking it would cause the car to die if we held it, well it didn't. there was next to no suction. So i;m beyond frustrated, so my friend and mechanic suggested we take it for a spin so he can see the lack of power, well he thought i was feathering it and i was at 2500 rpm trying to reverse and slowly creeping backwards, he thinks its my clutch but i've heard a messed up egr valve or system can do this. i'm so confused and need some guidance guys before I gut my cat...

could it be the clutch or the egr system?

there was a smell like burning clutch while i tried to backup, and i never grind gears or abuse this car. The previous owner did though i'm sure of it.

Don't forget to clean out the EGR tube too:



This is how it'll look when you get it all out with the tube attached: (Minus the broken flange... don't try to take the tube off the EGR with it on the manifold.)



Easiest way to take the tube out is to take the throttle body off and use an open ended wrench on the lower nut. Make sure to hit it with PB blaster:


Definitely clean out that EGR though. I had 160K miles on my car when I cleaned mine and it was almost closed completely with carbon. Looked like I was scraping out charcoal.

Barrymans B12 Chemtool is one of the best cleaners I've ever used for cleaning up throttle bodies and carbon deposits. Also, Seafoam your vacuum lines by sucking 1/3 of a bottle in through the brake booster.



That should fix your EGR issue unless there is a broken diaphragm. To test this, take off the upper hose and press up on the diaphragm. Hold your finger over the hole, if the diaphragm moves down, you've got a bad EGR. If you're not sure, borrow a Vacuum Pressure Tester from Advance Auto Parts and run a line to the top hose hole and then have the tester suck on the EGR. Watch the needle to make sure pressure stays the same.
