Hi everyone, I'm desparate for help.

1993 1.6. Stock
Setting engine to base 10 deg ign timing causes massive loss of power, can barely get the car to move. I have to set the timing super high (18 -22) Just to get it to run anywhere near normal.

I'm assuming this will correlate with my issue*
Really bad misfire
Tore everything apart and redid the timing belt to make sure; everything matches up the way it should. Lobes, marks, tdc perfect.


Anyone experience this? I'm struggling.

Thank you!

Has the harmonic balancer sliped?

 

Exactly my first thought too.

 

how would I go about figuring that out?

 

Put cylinder one to TDC based on a soft rod in the number 1 spark plug hole then check that the TDC mark on your balancer matches the TDC mark on your timing cover.

This isn't the 100% way but if you're balancer has slipped 10 degrees or more it should make it obvious.

 

Yup, you guys where right! It was like an entire inch off. I made new marks and engine rune and sounds about right.

Still having spark issue though, new plugs and wires, proper gap; thinking coil pack :(?

 

Just a heads up, once the balancer slips, it keeps doing so, so your marks will be off next time. Time for a new one.

 

I can confirm that, even starting/stopping the motor will cause it to slip again.
