78 air intake probs

I'll definitely have to do that

Mine kicks out white smoke every now and then but its never kicked out black

And I agree I think my coolant sensor has a jank connection I took off some tape that was around the bullet connectors and the wiring looked pretty sketchy I'll probly try and rewire all of it

Now I'm questioning what year my car and engine is

I believe the sensor near the starter would be for oil pressure, but I suppose it could be for oil temperature (a modification someone made).  It's not stock.

 

He has a ZX P79 head.  Somebody ran the pigtail to connect it to the coolant temp sensor circuit but didn't finish the job.

 

Compare the image below to post 38.

 

 

If he finds a meter and uses it right it should be an easy job to find the bullet connectors to the coolant temp circuit then run some wire to the CHTS.  Can't get much simpler.

 

On the engine - there should be some letters and numbers molded in to the block beside the driver's (left) side motor mount.  Either N42 or F54.  1978 stock is N42, 80-83 ZX is F54.  They're both good engines. http://www.xenons30.com/Engine.html

Ah, a ZX head!  OK, that makes sense.  The intake seems to be '77/78, judging from the manifold vacuum ports and EGR.  EFI is probably '77/78.  Yes, wiring in the translocated CTS should be an easy job.

Okay it's starting to make sense

[ghetto_zhetto]

Okay so it seems one of the previous owners changed to a zx head for some reason my block is an n42

[ghetto_zhetto]

I've changed out my coolant temp and water temp sensor connectors and have not had a problem in weeks

Let's just hope it stays this way

I'll update if anything changes

[FastWoman]

Cool!  I'm certain that was at least 90% of your problem, if not 100%. 

[ghetto_zhetto]

Yeah its been running great but only time will tell if it fixed it

[ghetto_zhetto]

Sorry for the long wait, I lost access to my account for a while. 

but after replacing my coolant temp sensor, replacing the connections, and setting my afm back to factory my car runs great, other than it being old and sluggish

Thanks everyone for the help 

I have a fairly happy z
