Don't sidestep the idea of plug wires... TGP's are plug wire eaters, the easy way to check is to go outside and open your hood then, in total darkness look to see any light flashes, those are bad plug wires... :shock:  :drinking:  :drinking:  :bag:

Yeah...
I replaced tha plugz, plug wirez, CAT, and tha o2 sensor...

if its steal running like shit...
then I'm just gonna' replace tha coils az well...

I'm still trying to find out whats going on with my car...
it use't to run brand new...
now it acting really wierd...
it only tryz to get power when it feelz like it...
and tha take off iz really really slow...
nobody seemz to know whats going on...

Quote from: MajesticNo its not that...
I think its just tha small leak I got on my crossover pipe(I think?)...



Say I needed a coil pack...
could bad coils cauz a loss of power...
and by a loss of power, I mean "A LOSS OF POWER!", and gas by tha way...
cause I tuned it up, and replaced tha CAT...
and yeah, its still acting up...

yes coils can cause a ton of powerloss..if one starts to go bad, you will have misfires on one or both cylinders that the coil is responsible for sending voltage to..the car will run rough when it is missing and have a great deal of power loss.  You can unplug the ignition module and test the coils for proper resistance on the secondary and primary leads....I don't remember the specs off-hand, but I do believe there should be around 8,000-20,000 ohms of resistance on the secondary side and about .5-2 ohms on the primary side. I'll look up the actual specifications and then post here if nobody beats me to it.  But don't rule out other problems, check over the plug wires REALLY well and inspect for cracks/splits/burns/etc.......good luck finding the problem.
