Rough Idle - Loping Then Died?

[Scrat0351]

The MAF sensor (The first three-wire sensor located on the tube after the air filter) doesn’t have a 5V reference.

The supply voltage should be battery voltage with the key on, disconnected sensor, and measured on the harness side.

I will get it towed to the shop and let them figure it out.

It'll probably be cheaper than me guessing and not knowing what im doing.

I can change anything on here if I know what to change, but I am horrible at diagnosing.

Primarily electric, I don't know anything about it.

It takes a man to admit weakness.

With that said, you're not alone, I suck at electrical diagnosing as well LOL.

Well atleast I was able to sneak in some upgrades under the wife's nose.

Ordered a cold air intake and got a nice obd2 scanner as well.

If the shop doesn't charge me both arms and legs I might get some arp head studs so I can finally run those last 2 tunes that I've never tried.

The C1 and C2 connectors are at the PCM mounted to the engine block on the driver side.

The inner wheel well on the driver side needs to be removed to access it.

I totally understand your decision to take it to a shop.

Troubleshooting can be very time consuming and expensive on parts if miss diagnosed.

Please keep us posted on the progress and final fix.

Will do and thanks for all the support.

Those PDF's were very informative and helpful.

I just wanted to update you.

It ended up being the injectors.

I had them replaced with 50 hp overstock.

All is good now.

If you don't mind,

Was a tune needed for the new injectors?

What injectors did you use?
