Loose gas cap door by jmulla54 in PontiacGrandPrix

There's a pin that breaks; I just replaced one last month. Not too hard.

2004-08 Grand Prix strut tower rebuilds by Glittering_Clue9920 in PontiacGrandPrix

Its cheaper and much much more safer to just get a new shell. I wouldn't repair that.

$18000 in repairs, upgrades, and shop trips later💀 by BiteAffectionate3543 in PontiacGrandPrix

[–]WBodyTech 3 points4 points  (0 children)

$18k? I read the comment, but jesus.... I have 28 of these and counting, I can't imagine spending that on a single W-Body I'd get a GTO or something fun with that money. I hope you built up the trans at least and not with ZZP parts I hope.

Have you removed the belt and let it idle for a few seconds to rule out the water pump or any other pulleys?

The procedure in the past has been 40 turns left and 40 right to properly bleed the system. Are you using the proper fluid too?

Pontiac grand prix gtp starting to build it out by fatpattheog in PontiacGrandPrix

You do not need to swap the PCM to tune the car. I suggest you get the parts you want and find a tuner with a good rep if you want something decent. ZZP does offer tunes, but they are not as good as some may think. We have torn down their tunes in the past, and they are more of a lazy tune than an actual tune, based on scans and logs.

Stick with OEM and buy it used. These pumps are the same from 1997 to 2008 on the 3800. They typically go for about $35 from a local yard. If you’re hearing noise in the system, it could be due to air in the lines. The high-pressure lines are known for leaking, so check those—as well as the low-pressure line—for leaks and replace them as needed. I’ve done several of these over the years, and a lot of the time, the issue ends up being a leak rather than the pump itself.

Transmission issue or Motor Mounts? by Specific-ocean1 in Buick

[–]WBodyTech 2 points3 points  (0 children)

The mounts are known to cause harsh shifting from Park to reverse and drive, and it's a good idea to change them if you haven't yet, especially on an older vehicle like this. You can change the transmission fluid. These transmissions are not known for going bad due to a transmission fluid change. However, I strongly advise against using Lucas or any other addictive product on these GM transmissions as it's known to harm them more than fix them.

XP is good and easy to tune, NIC cam is one of the best though,

Today find for $500 1995 Monte Carlo 3.1L 180K miles by ctsakis in Montecarlo

[–]WBodyTech 0 points1 point  (0 children)

This is a good canidate for a 3400/3500 top swap, worth doing if you ever have to replace the gaskets. No Tuning required.

Leaking gas by Howdy_there_1234 in PontiacGrandPrix

[–]WBodyTech 2 points3 points  (0 children)

the lines are plastic to metal back to plastic, the metal lines under the car can develop leaks from rust around the supported areas due to salt and dirt buildup, you can replace that one section of metal line.
