I have a 1992 turbo td04h miata 1.6.

I swapped in a 1990 miata motor cause the other one was bad.

everything seems to be bolted on correctly and no leaks.

i just started it today and the engine ran a bit weird. Kind of like a lawn mower. The distributer is still lose for adjustments. The problem is...

I start the miata, slowly let go of the clutch, then the engine dies... I am stumped.. What could be the problem?

 

Miatas have distributors? I don't think you have a miata engine, bro.

 

sorry, I meant the miata crank position senser. The cylinder shaped deal attached to the back side of the intake cam rod..

is the car in gear?

 

Is the timing good?

 

The car is not in gear.

We pushed the car unto the driveway. I noticed that the clutch and brake was really lose and grabbed some dot3 and tried bleeding them in for about 10 minutes.

Then i started the car up in neutral. With my foot down on the clutch pedal, it runs ok. (sound a bit like a lawn mower) As soon as the clutch becomes completely released while in neutral, the car dies.. (!?)

 

i set it to (10) top dead center, intake cam and exhaust cam straight up.

As far as timing.. could that cause the engine to just stall when the clutch is fully released in neutral?

 

I figured the car was in gear and you were trying to go forward...

So it doesn't try and move forward when you let out the clutch?

What if you give it a bit of gas as you let out the clutch.. still die?

Could the transmission be fux0red... binding of some sort?


Honestly not really sure, just figured I'd throw some random stuff out there.

 

Eh? That's not set properly. We'll get to the clutch issue after the lawn mower issue.

 

lawn mower issue: figure out what exhaust connection isn't tight/secure. If it's not obvious, I would start by making sure the coolant hard line from the heater core is bolted over the manifold at the #3 runner instead of under it.

 

I don't think he's talking about a leak. From what I read it's not running smooth. :dontknow:

This sounds like a bad case of retarded timing or fucked ignition.

 

Or running on 3 cylinders.

 

Which would be teh confuckled ignition. Can we get pictures of your timing setup?

 

I retightened the bolts on the exhaust and adjusted the crank position sensor. It seems to sound great now.

Now I cant seem to figure out why the car dies when the clutch is released. (!?)

Wow, the engine runs so rich. When i pump a little gas, the engine dies all together... as if i flooded the engine. (400cc injecters)

Is there a way to manually tune this link engine management right from its viewing screen? I dont have any of the applications and linkages to it. (never tuned it before)

 

Even still, your car shouldn't be dumping that much fuel into your engine. What other fuel modification have you made (rail/pump, blah blah)?

 

here are some random pictures of what im doing.
