at idle (800 rpm) the ign timing isnt even 0 degrees...

and cam timing is correct!!! anyone have an idea???

 

make sure the cam is top dead center with the crank

 

are you saying you cant get the igniton timing to 0* even when you turn the distributor
you might have jumped a tooth on the timing belt...

 

no cam timing is fine...(I will double check this week tho)

but even with the dizzy all the way to the firewall its only at 0 degs, not even....

 

what engine?

 

d15b2 w/mpfi swap and si cam (1/2 tooth retarded)

 

look at timing gear on camshaft - it should have 3 marks on it, 2 directly across from each other that are used to align the DX/STD/HF camshafts by lining them up with the top of the head - the 3rd mark is at about 7 o'clock - on the Si camshaft, this mark aligns with a mark on the inner timing belt cover and the other 2 marks are ignored (they won't be at the top of the head)

 

also make sure you have the plug under the dash shorted.

 

the plug is in my engine bay and yes it is when we check the timing...

and i installed the si cam to 1.5 cam timing specs but like i siad b4 it is a little off, 1/2 tooth but that is because of the cam. And even that wouldnt throw off the ign. timing this much....

You probably have some wiring issues with the mpfi swap. Did you just complete the mpfi swap recently and notice your timing is off?

 

I have to check a write up that I used when I did the mpfi swap on mine. There are two wires/pinouts that if you get mixed up will severely retard the ignition timing.

 

If you have any codes get them fixed. Certain ones throw timing severely off.

 

yeh i jsut did the swap...i thought that too about the wires, although Ive double checked them a bunch...

the only code i have right now is a 14(EACV)

when i first started it up i hade a code 4(crank angle sensor) but it went away after that first start up, but it still worried me.

but i checked the wiring and everything; seems ok...


let me know

 

yeh I think c1 and c2 may be going to the wrong spots....Ill double check this when i get home this weekend....

the diagnosis seems to fit my problem exactly...


Ill let ever1 know....

any other suggestions still welcomed

funny thing is if this is the problem why arent I throwing a code 4 anymore....

 

Good luck, those were the pinouts I was thinking of.

Nope I had it the right way.

We notched the dizzy a bit and at 800 rpms we got the ign timing up to 2 degrees!!!haha


please someone help...

 

are you using an adjustable cam gear? if so, i had the same problem because some aftermarket companies sell the same cam gear for 88-00 SOHC civics when i know for a fact there is a difference between a stock Z6 and a stock Y8 cam gears. i was reading at bout 12-13 degrees, and had to adjust my cam gear a little less than 1 degree for it to get the timing within range.

 

if it runs smooth maybe the crank pulley is just bolted on wrong, like if the key was missing and it turned

no Im running stock gear, si cam installed as close as i can to 1.5 marks(but its 1/2 tooth retarded obviously...)adj. cam gear coming soon...

thats the thing it runs pretty good, but I know it could b better. I only have a cel 14(EACV), it bogs at partial throttle but we think its just a vacuum leak due to eacv...

bolted on wrong ? not sure, ill check...

 

Did you ever remove the dizzy, its possible (for some people) to put them on 180 degrees the wrong way...that could be the problem.

I had a similiar issue with mine, but the cam timing was off like 22 degrees or something. To avoid the posibility of a mismarked crank pulley, pull off your spark plugs and stick something long into them until it touches the piston, turn the crank pulley until the long rod (or whatever) reaches its peak, then take a look at your cam gear.

no dizzy is on correctly and cam timing is 1/2 tooth retarded(approx. 4.75 degrees).

How is it off 1 half tooth, and even if it was, I 'thinkk' it'd be more degrees than that. How many teeth on the cam, 18 or so?

the difference is because the cam is from a d16a6, and its slightly off due to deck height i think. heres some threads

i think the gear is 28 or 38 teeth...

Interesting, wasn't aware of that. So you are POSITIVE that you are only off 1/2 tooth. If your not, I would use my idea of putting rod (or something) onto the piston dome and spinning the crank pulley to find out for sure. Like I said, I had the same problem as you do, couldn't get my timing to move past 0 degrees, cam timing "appeared" to be on judging by the marks, but it wasn't.

I can check...what do ido exactly, bring it to tdc and #1 cylinder should touch the rod and make sure its the furthest point up???
