have you ruled out an exhaust leak? the smallest of pin holes has thrown mine off by a full 1.0 af ratio

FIXED!:icon_bigg

the fact that you stated your going off of busted (or unreliable) gauges would signify postponing most head scratching until you have reliable data.

$1.99 reg/ $2.40 93 :D

RD= loudest between 2200-2500 rpms as the ecu advances timing. the info is there, you just have to search;)

60psi base + 10psi boost= roughly 79psi fuel pressure, WAY outside the stock pumps abilities. good pump comparison

agreed 7m's arent PRONE to rod knock more then any other motor out there. this appears to be a HUGE misconception. either it was NOT repaired properly, or something else happend most likely involving lack of attention to the oil or trash floating through the motor (again, some didnt stay...

LMAO, the cost of the motor= cost of the swap :runaway:

The computer assumes the car is at operating temps if the ecu temp sensor is disconnected. You'll get a code, but idle should still be 14.7af ratio or in normal closed loop range. And open loop idle for me is in the 12's af ratio if i disconnect the o2 sensor (forcing open loop). It doesn't...

Take that boost leak tester you rigged up and grab a piece of silicone coupler, stick it on the tail pipe and pressurize it. Helps immensely with finding tiny leaks pre o2 and you can take your time inspecting all the connections and joints on the exhaust system.

$30 bucks or so at autozone makes for a quick repair of the water temp sensor (ECU). not sure how much at the dealership.

me two!

good catch aspec, didnt consider that!

youd think it would splice in right before the harness hits the firewall, save maybe 2-3' of wire for the bean counters....

oil lines to and from filter head to cooler and vise versa. Not 100% on the zip ties but they will do until i can get some brackets to secure them.

pic 1 no choice but to stick it in front of the inter cooler until i can add a different IC that mounts horizontally with the front bumper and lower rad. support. The OC is to thick to stick behind the IC with the condenser and is nearly as long as the radiator. It wont fit between the...

pic 1 is of the craptastic stocker. Pic 2, i reused the stock filter head with a spin on adapter and the bypass valve shimmed shut with a bolt, no play to open at all and then capped the hose end off. The spin on adapter has no adjustment to where the hose ends face in relation to when it...

the goods, fourth pic is thermostat, or "thermopellet" as the mazda guys call it. Oil bypasses MOST of the cooler through that hole and when it hits the right temp the thermopellet expands and blocks that hole shut forcing oil through the cooler only. In fifth pic you can see into the...

Lmfao!

The filler cap being removed is the leak?
