k so an update i got my exhaust buttoned up and now its actually bearable instead of this open header business. I changed the spark plugs and adjusted the IACV screw and it idles ok but its still not right especially when its cold.

So ive come to the conclusion that either my ignition timing is off, my fuel filter needs to be changed or my IACV needs to be cleaned. Also i still havent swapped my dizzy coils yet but i will soon because it was 1.1ohm instead of 0.6-0.8 so im thinking it could be gone.

ne other ideas why the car will idle rough when cold and when its warm it will die randomly.

Start with the obvious.

well i read it could just be the resistance in the leads for the multimeter but im gonna check that tommorow.

K update for tonite, i drove the car for a good hour and a bit and its acting real messed. It will stall out almost 100% the time when i let it idle unless i hold the gas pedal slightly.

When there is a load on the engine (in gear) the car has a tendancy to bog (feels like it has no power) in the lower rpms and then it will just kick in randomly and cut out and kick in (mostly 1/4-1/2 throttle).

I used a stainless steel braided clutch line instead of using the oem one and it doesnt seem to have enough pedal pressure to engage the clutch in first gear (very very tough to get it into first). im not sure if this could be related to the power issue, im worried that my stage 3 CM clutch is messed up or something although it grabs fine if i shift at redline.

so anyone got any ideas what the problem could be?

timing belt jump a tooth? ignition timing off? weak spark? fuel filter needs replacing? motor is fucked?

 

you know what's funny... this same **** is happening to my si right now... what the ****... my car is pissing me off

so far all i did was replace primary o2 sensor, fuel filter, and cleaned out my iacv... but the same **** is still happening... got to check my ignition timing next... soon i might be replacing the dizzy and the wires next

 

well if u figure it out lmk man cause this **** is pissing me off and im suppose to be going away saturday for my b-day and im suppose to be driving to niagara falls....

 

**** let hope we both get this fixed soon... if you get yours fixed let me know also, i want to try whatever you do. my car is my daily driver and so far i can get her to run most of the time, every now and then it will suddenly bog, then after i let off the throttle and reapply it it goes away.

2 days ago it did shut off on me and the car was hesitating when i got her started a couple of times... after dying and my restarting a few times it just dissapeared... i was lucky i guess...

right now it running fine so far... but i'm scared sooner or later it might not even run or something... i know my car is due for a timing belt replacment pretty soon i'm at 93000+ miles, so i think that's what could be causing it as well... maybe it slipped or something from being old... but what do i know...

 

best thing to do is start eliminating things, ive tested my MAP, TPS, IACV, spark plug wires, injectors etc and eliminated them from being the problem. changed the spark plugs and it seemed a little better until i went and drove it around and it got worse again making me thinking its a dizzy problem or its running too rich.

 

yup... i have also tried eliminating things also... i checked the injectors, map, tps, iacv, and spark plugs. checking my timing tomorrow so hopefully that could bring something up... hopefully i just have to replace the dizzy and wires

 

just changed the primary coil on the dizzy and that didnt do anything, messed around with the plug wires and that didnt help either.

Gonna replace the fuel filter soon and see if that helps at all. May go pick up some seafoam aswell and see if that will help anything.

im running out of things to check, i really hope that its not a timing belt problem

 

changed the fuel filter and it didnt change anything so i dont think its a fuel problem.

ive read there is an access hole that u can use for a timing light and checking TDC on the crank pulley but i cant seem to find it. i wanna make sure that everything lines up at TDC.

LMK

 

ok when the car is idling u can hear the engine pulsing. its like brumm brummm brummm brumm consistently. when u rev it up u can kinda hear the same thing but not as much.

im wondering if this is an ignition problem or a timing problem or a fuel problem.

More likely an air problem.

 

so u think its a vacuum leak? im starting to think maybe the IM is leaking because i did remove it to paint it flat black but i torqued everything ot spec so it should be good and i dont hear any vacuum leaks although it could be under the IM.

If it's revving up and down it's a good bet taht some unwanted air is getting in somewhere.

Spray around with some carb cleaner, see if the engine speed changes when you hit a bad spot.

 

would a leak on the IM cause the engine to stall after idling for like a couple minutes?

 

what's your vacuum reading at idle... i know on my car it isn't a vacuum leak, because at idle my car is around 18-20hg (which i was told was normal) and when i forogt to plug up a vacuum port on my aebs intake manifold it idled around 1.5k and my vacuum was around 14-16hg at the time. i'm thinking in my car it's an ignition or timing problem. still boooo on the problem though... hope we both figure this out though.

 

so u have an aebs IM on the engine? i remember reading that u have to remove the IM support bracket so the bottom of the flange will sit flush on the head. Check that out, could solve ur problem and could solve mine because the IM was the only thing i removed before re-installing the engine.

 

check all your vacuum connetions, and like someone else said, spray carb cleaner around your intake, vacuum lines, etc. to see if you can find a leak.

 

i have the support braket removed... i have no leaks i checked this afternoon... my friends mechanic said i most likely have to replace my dizzy

 

well i just drove the car for the weekend and this is basically how it drives.

When it starts up it idles up and down up and down. It will almost stall out but for the most part it wont stall when cold.

When the engine warms up it will run fine in the upper rpms but in the lower rpms it will bog and feel as if its lacking power. If i start in 1st and try to peel out the car will basically stay at a steady rpm and then all of a sudden jump forward and it will feel like its suppose to. Also sometimes when im driving and im coming to a stop the car will just die. Also if im driving and i put the car in neutral (not going too fast) it will die and then when i put it into second and release the clutch it starts back up again.

Anyone have any ideas wut the hell the problem is. Also in 1st and 2nd it will sometimes become really really jerky which im not sure if its related or not but its annoying as hell.

 

someone has to have experienced this problem before. I just sprayed WD40 on the top of the IM, near the injectors and around just about anywhere except under the IM for leaks and couldnt find any. im so confused as to what could possibly be wrong. And to add to it my radio wont shut off when i take the key out of the ignition. im not sure why its staying on but i should be able to figure it out i hope.

 

i did some research dude... try checking out the ignitor and try checking out the main relay. also make sure all the contact points are clean and free of any gunk...

 

hmm would the main relay effect the car when its driving though? I could see the ignitor maybe messing around with it maybe?

 

well i was looking around this site and those seemed to cause the same problems as us and people had looked at those parts as well. mostly the ignitor was the problem occuring to most people on this site when i searched. i'm going to swap mines out to see if the bogging still occurs. right now my car my car is still running fine again luckily ... hopefully it won't come back
