Check the tightness of the turbo to manifold bolts. I had a loose turbo/manifold connection and car felt fine possibly a bit down on power, but under boost it would give off a loud hissing sound. Also look for soot marks indicating a leak where the exhaust manifold meets the head.

Might be worth having a dealer hook up and see what they find. But that has a small cost. If you have time, wiring diag. is your friend. Get down and comfortable with checking for voltage, ground continuity. Look for anomalies. Also meter for broken wires. Try disconnecting lock solenoids...

PDL, interior lights and signals could be connected through security system, and/or BCM. Perhaps try checking wiring to related components. Is the issue intermittent at all or constant? Any codes for CANBUS hiding in memory? Commonly wont activate CEL.

Well if you are having TB issues, Do you have access to a known working TB. Swap it out and check to see if the issue persists. With the issue manifesting after some time into your drive, perhaps the motor in the TB is failing. Heat affects the way electronics/electrics work and when they get...

Look into the condition of the connector to the Accelerator Pedal. Look for corrosion or loose/damaged pins. You might have an issue with the pedal, or the wiring related to. Also ensure the connector to the throttle body is in good condition and seated properly only because that seems to be...

Bad ground? Check <here>, from my post where I had issues with my signals and some other circuits.

Accessport does not need to be connected once the tune has been loaded to the ECU. However there are some features when it is connected (Logging, sensor monitoring etc). The accessport is a flash tuning device and rewrites the parameters for the car. Your start issues might be normal for the...

Your car looks to be in nice condition. What are your plans for the car?

Welcome to the forum. You might have a leak where the transfer case fits to the transmission output. If you remove the transfer case, sometimes you can clean up the surface where it meets and reassemble...if you are lucky. However, if the trasfer case is leaking itself, there are not gaskets to...

Fast in the corners takes money & talent...fast on the straight takes money & more money, lol I love 911s. But Im the guy who will put a roll cage in it and paint it flat black. Most Porsche buyers think of it as an expensive suit..."it makes them look good!". I prefer to think of it as...

Ive done absolutely nothing with the Speed6 except carry all the fun goodies around in the trunk. The car gets driven about once a week to work and back just so it dosent sit. The lack of garage has severely decompressed my energy to invest time. I feel like a such a sloth and looking at the...

Alternator shops use a solder with a higher melting temp compared to whats used in standard electronics. See if one of them could help get a better connection.

Good to correct something that was going to cause you a great deal of hurt down the road. What are your goals for tuning? Depending on what you want to reach, with the miles on the car and unknown on the engine you might consider some of the following...(Suggested by Will @ PD tuning in his...

I purchased a rebuild kit from mazda. Easy to do. Dont think I actually needed it at the time, but if yours is leaking...its time.

I would pull the clutch pedal bracket out and check for cracks. I didnt have the exact same issues, but some similarities. I also ended up with the Fidanza/Luk combo. I also found that I had to bleed the system to the connection where the flex line meets the hardline below the fuse panel then...

Received my hat today. Thanks @Raider :thumbsup:

You look like you are performing better. You arent crossing your arms in the corners like in the vids from way back. You also look more relaxed or composed in the seat, which goes along way to make the car properly fast!

Excellent choice grabbing the Autotechs. And yes that is very dirty. Be sure to disassemble and clean the spill valve, some people skip it and have troubles later. Prolly everything you will need to know can be found <<here>>
