Ya I just put a new cap and rotor. Since it's been a while, I'll list all the new parts I've done so far trying to fix this issue.I agree with the others. That 6 hole is dead. Not for nothing but have you pulled/looked inside the distributor cap and also checked the plug wire?
Another thing is all the plugs like 3 sets in a row look black and fouled out. But yet the afr gauge shows lean and it pops in the intake under load. I've always read plugs but I'm just confused at this point
I know it's not the rings, motor ran amazing and compression was great before the top end kit. I definitely could have about too tired or something. This is the first time I've done a hydraulic rollerIf the cylinder has low compression it will still try to fire but it looks like all the plugs are showing an over rich condition.
Do a compression test and if it’s low follow up with a leak down as it could be a bad valve issue or rings.
Ya I'm going to do a compression check tonight. Then pull the intake and noid light the injector and move it to another hole to check to make sure if the injector is working right or not. The inline spark tester showed spark but maybe it's weak. Or could the TFI module cause that issue also? And I'll have a buddy come over that has a few of these cars to help me do the valves over again just to double checkThis is not strange at all if you are a cylinder down.
@Noobz Unspent fuel in the exhaust stream should be picked up by the wide band.
See post #53. Also, with all the plugs looking stupid rich I would think it would pick it up on either side.
@Noobz - I would think that regardless of being a cylinder down or not the AFR should be showing rich if the plugs area showing rich. Unspent fuel in the exhaust stream should be picked up by the wide band. Maybe I am just not looking at it right but it reading fine just makes no sense to me.
I learn from you all the time. It's nice to return the favor occasionally.Okay, there in lies my lack of knowledge on how an oxygen sensor works. A person would think to focus on the word "oxygen" but I chose to ignore. Doing some reading now to educate myself.
With all that what's going on makes a lot more sense now so thanks NoobZ!
I installed it on the driver side, I think it's bank 1. I wasn't able to work on the car today had to go pick up my truck from the shop, stupid recall crap. Also talked to a tuner buddy who helped with my supercharged f150 and he told me the bosh style pink injectors I got from lmr are cheap crap, and since I already had 2 go bad he's sure that the one in #6 is bad too. So I ordered a whole new set of Ford racing injectors they will be here Friday either way. But I'm still going to do the compression check tomorrow. He doesn't have a way to tune any type of factory computer so he can only help so much. I appreciate you guys you have really been a big helpWhich bank did he install the wide band on? If on bank 1-4 then it won't get picked up.
I can't really tell if it's white I just assumed looking in the review. But if it was a head gasket wouldn't it be doing that in every gear. It's literally only secondWhite smoke usually means head gaskets.
I'll check it out this afternoon when I get offIt would do it the most when you pull the hardest for the longest amount of time.
You're putting less torque on the engine at WOT in gears 1 and 2 than you are in 3 and 4. A small bit of water in a combustion chamber is all it take to make the exhaust turn white.
If that's the case, I would think you would see an O2 code. Might be worth a check.
