Need Help 94 5.0

Update......car is FIXED,no o2 sensors needed. Apparently when I put new plugs in it one of them was the wrong type and mixed up in a different box or something,not sure how i got that plug. But in trots runnin perfect again

Good for you for fixing the problem. However, aren't you at all curious how your EFI car is running without O2 sensors? No EFI vehicle runs well without them unless the ECU has been modified. If you truly do not have O2 sensors it would be in your best interest to remove the passenger side kick panel and remove the ECU and inspect it.

Imagine that something much more simpler than a sensor...like I said people get on these forums and overthink :poo: all the time

Or underthink? With the symptoms the op described I don't think a "wrong spark plug" was the problem. Smells a little off to me.
 
Seriously.

This forum, much like any forum, has people that completely geek out on this stuff and have the ability to diagnose issues from thousands of miles away. Years of experience, ample knowledge, etc, etc.

Yet people come in here, into the 'community' so to speak, where the regulars come in the morning to browse as they drink their coffee, and have the gall to ask us what's wrong and THEN say that we have no idea what we are talking about.

But hey, don't take our word for it. It's not like it's all over the internet.

I must have missed the post where you guessed it was an incorrect spark plug? My 88' notchback has no O2 sensors in it but I can explain exactly why it can run without them where as the dip chit OP can't explain why his can. It's not cool to be stupid about your own car in my opinion especially when looking for help on online forums. It makes it very difficult to diagnose if somebody doesn't know anything about their car and what modifications were done to it.

I was thinking that exact same thing.

"Hmmm,..let me see. I'll just reach in my spark plug drawer......"

Let's reflect on this for a minute.

Am I the only one that checks plug gap before installing a new set of plugs?

I think not.

That means that every single plug that goes into the engine has to be in your hands before it's installed, examined closely enough to check a gap measured in thousandths, and yet somehow, ol dude here managed to put a spark plug in the engine that was so wrong it caused the engine to run badly?

How wrong would it have to be?

I'm no expert on how long a reach has to be when screwed into the head before the piston would hit the plug and close the electrode, but IMO, that doesn't happen until there is some serious domed piston sticking up in that chamber.
I spect that this guy has a flat top at best, so I'm thinking a "wrong plug" would have to be reallllyyy long.

Maybe if he screwed a bolt in the head, that would definitely cause it to run bad.

Like I was saying.. smells like someone stepped in something.

And now that guy just graduated from don't know what your talking about to
:bs:er.

Or then again, maybe he didn't notice that the threads on the plug were an inch longer because they were dripping wet, and slippery.

Because they were sprayed with WD40.
