Who makes the best body panels? I'm looking to purchase door skins and want something that will actually fit.

I connected a bulb between pnk/blk terminal and the ground terminal at the maf connector and the bulb was bright. I also connected the bulb between gray/ red terminal and ground and with my power probe supplied voltage  at b6 with connector off and bulb was bright. I also checked for short to power and short to ground. no problems found with any circuit. I am checking with maf disconnected and not back probing.

I tested all 3 circuits and even did a load test to eliminate and any issues. the wire at b6 is a grey/red wire and I have 5 volts at it all the time. as soon as I plug in the connector the engine starts to spudder and stall, the maf readings stay at 3 g/s.  I have been messing with this for 3 weeks and it gets expensive when you just throw parts at it lol. I appreciate your help. I think my issue is elsewhere but its affecting maf.

I just checked the MAF circuits again. according to the shop manual I should have 2.50 volts at B6 terminal at the ecm key on engine off and 2.48 volts engine running. I have 5 volts at the terminal. any idea what the correct voltage should be?

hello everyone im hoping someone can help me diagnose my issue. MY car will not run with the MAF connected. new LT1 maf and translator, ecm, air temp sensor, ignition module and coil. tested my grounds at the ecm and all ok. checked for vacuum leaks nothing found. BLM at 128 fuel pressure holding steady at 40 psi. it will load up and stall as soon as I connect the maf sensor..load tested the maf circuits and all passed. any help will be appreciated.
