Random misfire and ticking?

[kylecm85]

So I have noticed on my aeroforce that I am getting misfires. Like on the 15 minute ride home I had 4? Is there something I can look at. I pulled the plugs and found that one looks a little off. I will post a pic with this. I was checking the plugs to make sure they where tight as I have a ticking noise.

I have listened all over the engine bay for the ticking noise. It' seems to come from the bottom end more so than the top.

New tune? Maybe it's running too rich? What tune do you have on there now?

 

[kylecm85]

It's a sct canned tune. Bought it pre loaded. It's been on there for over a year now with no changes. Thinking its time for a plug change.

How many miles on those plugs? Did you use an octane booster?

 

[kylecm85]

Probably about 25k on the plugs. Never used any octane booster. Always used 93

Scan the computer to see if there are any pending codes for misfire.

No codes for anything. Wondering why it shows misfires on the aeroforce but no codes ever. Could the be that small that they don't cause codes?

 

[mineralgoogt]

It takes a ton of misfires on a Ford in order for it to store a code.

I see that. I'm just going to change the plugs and be done with it. Might just try to blow the thing up. So I can build a motor.

That plug actually looks like it was loose. And u can always look at mode 6 data. See if there is any history of a miss. If u don't have a code. Look at mode 6. U may find something

How do I look at mode 6?

 

[Alfiedagr8]

Some scan tools have that option. Even some cheap ones.

Ok that's cool. Well i have a cheap scan tool. I will check it out.

 

[Stang613]

Any ideas? Was the plug loose?

 

[kylecm85]

I have not had a chance to scan it. But I made sure all the plugs where tight and they all seemed to be. Will have to mess with it this week.

Did you ever figure out about this? I just got my aeroforce and its giving a couple of misfires on everyday driving around town. My friend told me a few misfires on normal driving is within normal parameter as long as it doesnt go past certain threshold and throw a code. Can someone verify this?

 

[kylecm85]

I have not found the cause. It has not thrown a code. Going to change the plugs once I can find them. No one in town seems to have them in stock lol.

Get some autolite ht1's from rockauto.com and dont forget to use the discount code. Comes to like $60 shipped for a set of 8.

 

[kylecm85]

Don't I need the ht1's since I don't have F/I?

 

[JeremyH]

Sorry ment to type ht1, fixed.
