I finally got tired of trying to drive in traffic with a 1700rpm idle and decided to get serious about fixing it. After reading all the threads, I found out the problem was something that no one has mentioned - weak throttle return springs!
Things I tried first:
1) reset PCM - no noticeable...
Before taking my Viper to the shop to determine why it is down 80+ HP, it was suggested that I check the cats. How do I determine if they are clogged and can I get a gross idea w/o having to find an exhaust pressure gauge?
I took off the driver side cat and can't find the brand that the...
I finally had my 97 GTS Dyno tested and the #s are low for the mods on the car (most were put on before I bought it). Peak Hp was 418@5500 and torque was 465@3700 with an A/F ratio starting at 13.5-14 @ 2500 and dropping to 12.4 by 5000. These don't seem dramatically improved from stock
My...
Finally got my Viper back from the brake "incident" described elsewhere and had my Fikse FM/10 wheels polished while waiting for parts. AWESOME!!! Took quite a while (6 weeks), but they look dramatically better than even the new wheel I bought as a repair - there truly is no comparison. Pricing...
Dropped a Mov\'it brake caliper on the freeway - aka \"case of the missing locktite\"
This is a warning to all Mov'it Porsche Big Red brake kit owners - ensuring that whoever installed your set used proper locktite/lockwashers and torque settings is really, really, REALLY CRITICAL. There is a...
I finally got around to installing interior carbon trim and pedals - quite an improvement for $220 total. The carbon trim is very easy to install - just clean the dash lightly with carb cleaner or clear solvent, warm the pieces in the sun and stick. The pedals were a pain though. It took me two...
It's starting to get warmer and I figured it's about time to determine why my temperature control is useless. AC blows 100% cold and heater blows 100% hot regardless what angle the control is at. The unassisted fan just blows hot air right of the headers of course, but I would like a little...
My 97 GTS often pauses at 1500 RPM for about 20-30 seconds when decelerating from 2000+ RPM before going back to a normal idle. This gets obnoxious when trying to coast down while waiting for someone to get out of the left lane because it only happens around 20-30% of the time, forcing me to hit...
I am going to upgrade my Viper this summer w/ new/ported heads and 1.7 rockers. I have a set of Crower rockers(+ cromoly rods, springs, ti retainers) that came uninstalled with my used 97 GTS. Should I just use these(free) or fork over the extra 1500 or so for the TDs? I am not going to race and...
