Probably need to clean/adjust your IAC sensor. TPS may need adjustment as well. Scott

Most likely it is the accumulator. Hard to find part now. But rumor has it that a source has been found. I actually bought a used one this summer to replace my failing accumulator. Don't drive the car until you fix it. You may burn out the electric motor and/or loose your braking all together...

Couldn't agree more..great service.

I had the same problem with my GN this summer. Felt like something was loose. Put the back of the car up in the air on jack stands using the frame for support. Slide a floor jack under the differential and raise/lower the rear end. Watch the motion. Mine went up on pretty good angle towards the...

Ramchargers Dual Fan works incrediably well. Fairly cheap, too. Might want to clean out the radiator as well. Lot of guys have good luck with a product called RIM-25 (I think). Do a search on that.

I installed a Rollmaster timing chain a few years ago and almost imediately started chewing up serpentine belts. Initially, I blamed the new timing chain. It appeared that the crank was not lining up with the water pump. I even shimmed the water pump pulley out more. Problem was still there. I...

Check the bolts on the bracket that mounts the air conditioning compressor to the block. They are known to back out and cause the bracket and pulleys to "swing" out. The belt then rides on the lip of the crankshaft pulley which will eat it. Been there... Good luck

.63 hsg with ported wastgate hole for THDP. standard actuator, Mobil 1 every 1500 miles, has approx. 7600 miles on it. Asking $385

Kirban's Performance has a good book out on the notorious window rattling on these cars..mine included.

I assume you have you have tightened up the actuator arm ? This will overide the chips boost settings. I have had wastegate pucks hang up on my THDP which caused similiar issues you are seeing. Try disconnecting the actuator and swivel the puck armature on the pipe. You may have to remove it...

BINGO..Having had two different mechanics look at my Chevy S-10, neither one could resolve the No power after a hot re-start or the lack of RPM. They chalked it up to either Carbon build up or a bad cataylic convertor. I had put an old K&N filter from the GN on it a couple of years ago. The...

I tried all kinds of cleaners on mine with no luck..Besides the thing is like 18 years old..Bought a new one from the Dealer for about $100 or so. Picked up new fasteners at Autozone.

I have one on my PT-51 and it spools up faster than the stock set-up with out a doubt. But I have an Art Carr 9" anyway and spool up was never an issue. I actually went with it to stop my boost creep issues, which it did. With a 60 series turbo and stock convertor its probably kinda...

Very strange indeed..it might be the electrical connector of the cap. Disconnect the connector and plug it together a few times. That will clean-up the contacts. Replacing the cap is pretty cheap compared to the mechanical unit $200 or so. If its original, not a bad idea to replace it anyway...
