• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Contemplating finding a shop for engine "refresh"

    I've had a random misfire for years and years (decade?), and I think I have to consider it's a head gasket. The car has 131,000 miles. I've tried to find the problem forever, but I never have. I haven't done a compression test. It has a small lifter tick, too. So, I'm thinking a "refresh"...

    Smelling coolant

    Are 2005 GTPs (L32) prone to coolant leaks (supercharger or head)? My sense of smell is not good, but I swear I'm smelling coolant (thought I have for a while, thinking back). I do not notice any film on the interior windows (heater core), and the engine compartment seems smelly. The oil in...

    Strange cyclic running to rough-running (up to reduced engine power mode)

    Car was running fine, I came out on the road to beat upcoming traffic, hit a small chuck hole (would not have thought anything of it), felt a loss of power, car went to reduced power mode, got to parking lot, stalled. Stared it after a few times, on my way, went to loss of power. Continued...

    What is this part mounted on a '05 GTP supercharger ?

    Well, I can't upload a picture that I prepared... It is a part mounted on the supercharger, near the EGR valve. It has an electrical plug and another line (wrapped with wire shield) - this line has a tee with a green cap that says "Hand Tighten Only", and this line goes to a block that has...

    Fitting rear pad ears

    Just an FYI: I had to grind the ears down on both of the inside rear of DuraLast brake pads (sanded with a belt sander). Now they move as they should. Touched them with paint to cover the bare metal. They must have been a little off on their punch. I'm very surprised the pad wear was even...

    What is a normal amount of misfires?

    I thought I solved my intermittent random misfires from vacuum leaks, but it really is just masked; they are still subtlety there. Now, they are much less, but I can tell the engine is somewhat groggy at those times. I run a OBD reader while normally driving, and the misfires show there. Some...

    Went into Low Engine Power mode

    Took a drive to check my brakes, and I lost significant engine power. I am seeing codes P0120, P0220, P0404, P1404, P1516 and P2101. I think I also saw an anti-lock brake system message. Earlier that day, I replaced front brake pad guide hardware. I mistakenly jacked up the car on splash...

    Misfires solved !!

    I have finally solved my random, intermittent misfires after probably 5 years of on/off frustrating pursuit. I've been at forums, questioned people, went to the dealer, and nothing really was getting at it. It was intermittently misfiring, hesitant or sluggish. (2005 GTP) Short story...

    70-series tires fit GT(P)

    Just dropping info. that P215/70R16 (standard steels -P226/60R16, 225/55R17) tires DO work on an '05 GT(P). - I came across a deal on 215/70R16 snow tires (that are probably typically on SUVs) and took a calculated risk. After fitting them, they do work. I kind of like the somewhat smaller...

    Carbon cleaning supercharged engine

    I've been wanting to do a carbon cleaning with water (possibly steam) but was deterred by the supercharger ('05 GTP). I've used Seafoam, but I've had good results just using water (on other vehicles). I recall, the GTP did not like to have the brake booster vacuum line disconnected or throttle...

    Intake vlv. cleaning with S/C

    I went ahead and (semi) blockheadedly sucked up SeaFoam through the brake vacuum booster line on My '05 GTP to do carbon build-up cleaning. I think it's OK to do, but not quite sure. First time for any cleaning for it; 121,000 mi. The engine did seem to run smoother. I'd guess changing the s/c...

    Dead Battery

    Here's the story: Used car as normal, the next day the battery was flat dead; Charged it; The next day it was dead. So I disconnected the positive and the standing battery and am charging it now. It seems to taking and holding a charge normally. I don't think it's a bad battery because... I...
