hi I have a ef 90 with a d16, it was getting hot and I flush the cooling system and instal a temp gauge, to do so i remove the distributor. When i put everything back on the car would start but only with to cylinders (1 and 2) it has the correct timing, the engine and the distributor, the spark plug wires are in other ( i didnt even remove them) and it has spark on 4 cylinders what it could be help me guys i need the car to work anyone have any idea?

 

Do you have the firing order correct on the car?

 

yep the are correct i didnt even pull them out i just unscrew de distributor and put it in to the side

 

So if you start the car and pull the plug wires from 3 and 4 cylinders there is no change in the way the motor acts at all?

 

It settles a little because it not fighting the unburn fuel thats been injected and when i plug them again it becomes very unstable again, sometimes even dies

 

sorry thats when i unplugged the injectors but when i unplug the spark wires it doesnt do anything

 

Are the injectors plugged in there snug? Check to see if you are getting power to the injectors.

Is the car DPFI, or MPFI or converted from DPFI to MPFI?

 

no is not a conversion is a SI MPFI and the injectors are activating i check the and they are clicking they have power and also there is no CEL

 

How do the spark plugs look? You said there is spark but maybe it's to weak. Does the spark from 1 or 2 ( the ones that are firing correctly) look the same as 3 and 4 when you touch them using a body ground?

 

im not shure how to tell you this i check the spark putting a screwdriver into the spark wire and ground in it to a valve cover nut they look much the same but if you have any suggestions...

 

Take out the spark plug from the head and test the plug itself. If you have good spark going through the wire, it would seem that maybe something is going on with the spark plug itself, corrosion, old plugs in general, etc. A spark plug can tell you alot about how a motor is running.

I would pull the plugs out of 3 and 4 and check them hooked up to the corresponding plug wire and touch them to the Chassis to see how good the spark looks.

 

i will do that now and tell what i will see in a minute

 

Take a pic of the spark plugs if you can and post them.

 

here are the pictures of the 3 and 4 spark plug with there corresponding wires

 

I meant pictures of the actual spark plug not of it sparking but sweet. How does the plug look? covered in anything? Does it have a strong spark?

 

theyare a little wet (fuel)

 

And the four of them are black...and now thinking a little bit i put out before the problem the spark plug 1 and it was brown so it was burning fine...(the spark plugs are new)

 

Well in all honesty I am out of options at this point...You have spark, you have fuel..they should be firing unless the timing is some how off *shrugs*

 

JEJE that makes two of us...besides the coolant sensor, what can make it be rich in fuel?

 

try doing a compression test on all four maybe if it got real hot it warped the head or did something to make it lose comprssion??? not sure but its a cheap easy test and can kinda give you an idea on the engine condition

 

replace the distributor
