So I’ve learned a lot in this process. Bank 2 is the actual culprit. Car runs fine until it goes into closed loop. It seems intermittent, while monitoring fuel trims while driving they seem fine, and not all the time but sometimes at idle they will increase up to like +22 or around there so...

Oh also forgot. Seemed like bank 2 short term fuel trim kept spiking up to +20%. Car is definitely running rich

So I’ve almost narrowed it down to a few things. My compression test kit just got here today. Going to perform that this weekend Here are my findings so far: - All 8 spark plugs are new (same ones from initial replacement) - coils are new, tested spark with each one. - Fuel injectors are good...

Going to attempt a compression test which i realize i have should have done this from the beginning before wasting time/money but you live and you learn lol. Noid test was good. The light was VERY dim. Im wondering if this is due to the impedance of the aftermarket injectors (Ford Performance...

I haven’t sent the ECU off yet. Noid test kit will be here today. I actually ended up sending the fuel injectors off to get cleaned to ensure they are 100%. I should get the fuel injectors back by the end of the week. Waiting to hear back if they found anything. I inadvertently drove with the...

While i wait to hear back about the PCM - if the cars camshaft timing is off/missed , does this mean my motor is most likely hurt? I uploaded a clip of the idle, unsure if anyone can hear the misfire or not :) I think ive pretty much covered everything i can. I may get a noid tester which...

Wow what are the odds. My late father in law (who i inherited this car from) Actually bought this ECU from FS1 so they are going to RMA it for free. Thanks for the reccomendation :)

Going to send PCM off to see if there’s any issues with it. No change with g201 ground. Made sure it was a good ground also by using it as a ground and checking voltage on the 8 pin connector. If the ECU is not the issue I’m almost certain it’s the camshaft timing. Car had a comp cams, valve...

Checked ground for g201 and I had an ext4/ ground wire not connected. I scraped off the metal to ensure I had a good ground but no change.

thanks for your help, it is greatly appreciated. Is this what the noise capacitor looks like?

You know what, this might be it. I was looking around the ECU/PCM earlier and did NOT see this ground anywhere. I will take another look tomorrow. Found this picture on youtube. For the radio noise capacitor #2, where is this located? I tried to look up and it may be near the coils?

None, but data logs show nothing firing on bank 1 according to my tuner. Has a noticeable misfire when idling

Starting to think the camshaft timing on that side is off. I’ve replaced everything minus fuel injectors and they are fairly new. Time to open up the wallet….

I didn’t see that, and I can’t find anything online. Are you able to provide pics?

EMF filter? Do you have a pic of that?

Update. All injectors have 13 ohm resistance. All connectors getting 12v Checked all fuses, everything seems good electrical wise

Hello, Having a misfire in my 99 cobra. Changed out spark plugs and coil packs, still an apparent misfire on bank 1 - passenger side. When I unplug the fuel injector on driver side, the car acts normal and sounds different. When I unplug ANY of the 4 fuel Injectors on bank 1 - passenger...

Yeah I changed out my intake manifold and it had a ton of buildup. So should I put it into the charge pipe before the throttle body? I assume I will have to drill and get a fitting.

Dang really these hoses might not fit. I swore everything I read said passenger side had the most blow by come through

Installed my first catch can. Read that the passenger side was the route to go on these cars. My procharger was a bit in the way but was wondering if this setup looks fine? I think I may get a longer hose for the intake side as I had to adjust my fitting upwards in order for the hose to not kink.

Looking for an OEM IAC valve for a 99-01 cobra. Motocraft Part # CX-1654. Let me know what you have.

I figured so, thanks for the advice !

Whats the difficulty on the install? Will probably get my mechanic to do it but didnt know if it involved dropping the rear IRS to replace. thanks!

What are the best IRS / suspension upgrades to improve handling, etc? Looking at doing Bilstein B12 coilover kit but wanted to know if there is anything else i should consider doing that will make a noticeable difference in handling. Thanks for any input!
