Tc light and engine light missfire#4 I have done all this 4 new plugs all new coil packs new air filter mass air flow sensor exhaust and intake Selinoids Then drove it 240 miles tc light came on first then check engine engine light. Help I’ve just about had it 2006 with 65000 mile on it. I was gthinking camshaft sensor next.

 

Welcome to the site, what is the code for the check engine light?

 

Like OB suggested, head down to your local chain auto parts store, where they will read the OBD2 codes for you. You could have saved a lot of money if you had done that first.
I'm in Cali, where they won't read them for you anymore, so I bought a reader.

 

Compression and leak down.


Which engine?

 

Says they replaced the "selinoids", so I'm guessing it's the 2.4l.

 

The scanner just said missfire#4

 

No it didn't! It may have displayed a code like P0304, and added a description like "misfire #4". What we are asking for is the number.


Are you noticing a loss of coolant?

 

Then I suggest you inspect the harness for the coil and injector for #4

 

P0304

 

Things needed for diagnosis:


Compression and leakdown test
fuel pressure test
inspect for loss of coolant
inspect wiring and connections to #4 spark plug/coil
have battery tested
