Wait a second, before you spend more money on parts let's do a leak down test and compression test to see the health of the motor. Also a smoke test can help narrow down some things as well. Have you check to see if your getting spark to the number 2 wire? Replacing your o2s still might get...
Bingo your o2 and cat plays a big role it's probably running rich without them. Unless you tune it out . Avg is 14 I can barely get 16mpg if I'm light on the throttle. Vacuum leaks can make it run rich also. Did you look at the old plugs to see if they were fouled or the condition when you...
Yeah I was looking at that but the hp/torque was insignificant. Before the tune ban people would just stroke it and just pass with the visual test and sniffer. Now there's less leeway, granted there still is a possibility you'll pass but I can't guarantee that.
1. Buy a diesel obs
2. Find a...
Try running the engine and unplug your map sensor check if it changes idle. Might be a bad sensor or swap it out for another there expensive tho if you have a friend or junkyard just wear baggy clothes and pay your $2 fee
Powermaster Performance 255 Amp Alternator - 48237
I found this on the oriellys website it says it compatible with the 5.7 350s and has the ad244 case was wondering if anyone has used this I think it's 255 amps looking to upgrade my voltage is dipping. I'm into car audio so I on the fence with...
It sounds a little deep, not much looks nice expensive, and if you don't route your wires right it'll burn your plug wires. $600 bucks for shorties hard to say if it was worth the headache. It's just eye candy to me
Is it knocking and pinging? Is the cats fouled how many miles on the motor , did you change the fuel filter also? Check for vacuum leaks and run higher octane maybe it'll help with the detonation. It's running rich that's why it smells like that
If your cats are bad it'll throw off your O2 readings. Since you don't need emissions you can tune them out. And 3 bad spiders is unusual. Are you installing them correctly I've seen people bend the connectors to the spiders and have it misaligned. And throw off everything from just the bent pins.
Do a smoke test and look for vacuum leaks. One of my hoses came loose and I couldn't figure out why it was running so rich. Do you have emissions like egr etc?
He makes those custom per order I'm pretty sure he can do a OBS harness. He does it pretty clean from the videos I've seen , haven't pulled the trigger yet on buying I think he made a video on how to make a harness also .
