Change valve cover gasket and running horrible and check light on

And u sound like my grandpa

 

Ok, so have you done the brake cleaner check yet?

 

When the sun comes up I’ll do that in couple hours

 

4 cylinder 2.7

 

I gave a like to the correct person.

 

$5 it's a vaccum leak. There are a myriad of hoses. Brake booster, pcv valve, back of airbox, front of airbox.. there's an easy way to do this kind of work and it is diligently. Worst comes to worse you didn't install the gasket correctly and it pinched somewhere during the install.

 

And that would run like shet and check engine light would turn on???

 

Arizona scrubs

 

Yes, a big vacuum leak would make it run like crap.

 

But would the light turn on

 

Valve cover leak is not going to cause a vacuum leak. Oil leak, yes.

 

I tried the brake cleaner didn’t work

 

Yes sir.. small vacuum leak would most likely pull up these codes: p0171 p0174

If it was a big whoopsie then you'll have a nice laundry list of codes

 

And they said the spark plug never had a gap I guess it bent when I was puttin it in

 

Then the check engine light came off but still running low idle

 

Try resetting the ECU by disconnecting the battery. Sometimes the ECU is acclimated to the previous setup and just needs to relearn.

 

It’s running better but there’s no light that came on and the idle is little bit low

 

But I guess was the spark plug never had a gap

 

I caught onto that pretty quickly too.

Well. He is old as dirt. So...

You mean a V4?
