just slight problems, what should i check

[Blackmount]

Like the title says, what should I check. I have two exsisting problems

I HAVE NO CHECK ENGINE LIGHTS but my CEL does work cause it turns on when i first start the car LIKE IT SHOULD

1: No cold idle...not a big deal...BUT it should cold idle so something wrongs....it just idles to 1k, instead of going up to 2.5-3k when the engine is cold.

2: Until i get the car nice and warm up to operating temp, it's really laggy feeling, like lacks in power. once it warms up it feels really good. sometimes it just completely bogs down like I'll give it gas and it just won't go anywhere... it free revs fine, definetly revs better tho at operating temp, I understand it's not at top form when its cold but its an abnormal to what it should be..

I don't think I have any vacuum leaks, i found one awhile back and fixed it, I am bonestock except no Resonator, 3sx downpipe, and Intake Hardpipe w\ cone filter. So pretty much stock.

Someone recommend me something I need to hook up a new Wideband to see but the car is mostly stock so there should be no AFR mixture issues if it's not throwing CEL's.

little bit intoxicated...not too bad.....but if any of this doesn't make sense..that's why hahahahahah

Cold idle is not 2500, its more like 1100-1200. 700 is warm idle.

[Blackmount]

just about every car I've had when you first start the car, it jumps to 2500-3000 right away and slowly goes down. Our cars ARE not suppose to do this? cause mine does it everyonce and awhile

[Miguel92.3000GT]

My car also idles at around 2.5k and feels the same way when I drive the car in the morning. So youre not the only one who has this problem.

[Mike-92RT]

my stealth doesn't rev at 2000-2500.... although it IS summer time.. i dont drive it in the winter, but im sure it'd probably go up to 2 or 2.5k when its that cold.

Check all your vacuum lines over again, check for leaks around the upper/lower plenums, and throttle body. Spray some intake cleaner all over those areas, and if the engine revs up, then you have found your leak.

Let me know how that goes. I will try to think of more things.

No leaks, this motor is under 50k old it should not have any problems, I discoverd a out of place green wire today that has been added that goes from a plug all the way back to the ECU...can someone find me a ECU Pinout of both 92 and 93 NON TURBO ECU's? (if there is a difference between the two years, i know the CAS is different)

My car is a 92 with 93 motor, everything wired according to directions from That other site.

[CoreyB]

Are you useing a 93 ECU? If not you problem is likely a sensor latency issue from the cam/crank sensors being different on the 93 engine.

[stealthee]

The latency issue is minor, and wont affect idle.

Also, there was no need to do a wiring change and use the 93+ CAS's just because you have a 93 engine. Youl could have just popped the 91-92 CAS into the rear head and, voila, no wiring changes needed.

[Blackmount]

I thought 93 was the year they used the Crank sensor? cause I don't have CAS sensor. I had to rewire the harness to use a Crank sensor

[stealthee]

No, you didnt. Your 92 has the old style CAS and your wiring was like so. You should have just stayed with the old style CAS and popped it directly into the rear head of the 93 engine.

[Blackmount]

I wasn't the one who installed the engine or anything. i got the car and the harness was all kinds of torn up. so best option was just wire it the guy started partially wiring it. and i wasn't aware it was as simple as popping the CAS into it. maybe i'll revert back to it...things i was reading made it seem like only option was to rewire it.

[stealthee]

The only people who HAVE to do a rewire are those putting a 91-92 engine into a 93+. The 91-92 CAS will pop into any of the 91-99 DOHC engines.

[Blackmount]

I was not aware. I'll try it when i get home from alabama and see if that makes a difference. I did remember today i had a CEL that came on randomly twice since i had the car, and then randomly went away.

[Blackmount]

I started on putting the original CAS back in yesterday when it hit me that The camshaft probably does not have the the slot in it for the CAS since the motor is a 93, I have a cam out of a 92 but I really don't feel like taring my whole motor apart, Mainly doing the timing, That shit sucked I don't want to do that till I have cams and a Kevlar belt.

[stealthee]

As said again. The 91-92 CAS will pop right into any 93-99 DOHC 6G72. No modification needed.

Also a kevlar belt is a huge waste of money. 99.9% of the time the belts don't break and when they do its something else that failed that caused the belt to break and you are still fucked.

[Blackmount]

I really don't want tare my engine apart to find out your wrong, I'm pretty sure I gotta pull my rear valve cover to pop out that cam seal so i can stick the CAS in there. plus I'm not sure what happend to the Original CAS plug, I don't remember Cutting it. I need a wiring diagram; Can anyone share?

[stealthee]

Listen, I have owned my 3s since you were in middle school. I have been around the forums for just as long. I have put a 93 engine into a 92 and have seen where others have done the same. I will repeat myself again,

THE 91-92 CAS WILL WORK IN ANY 91-99 DOHC 6G72.

[Blackmount]

I'll find out eventually. car's been running fine ever since i had a coupler slip off on me, i'm thinking it was partially off or something and it had a slight leak.


I really need to get a mount or something for it because what happened was the clamp slipped off a little on the bottom of the intake manifold and i couldn't see it, but it was allowing air in. I tightened it down good I'm sure last time but I did it extra this time.

[CoreyB]

Listen to Stealthy and use the 91 CAS in the spot that your current CAS is now. It may run ok now but the latency is a bad thing, your ignition timeing is currently off and gets worse the higher the RPMs are.

[Blackmount]

why the hell did people suggest the conversion in the first place? (not you guys) seriously doods

[stealthee]

Because people are sheep and don't take all the facts into consideration.

[Chris@Rvengeperformance]

Don't you need 1g heads to mount the cas to? I thought there was no bracket on the 2g heads?

[stealthee]

The whole thing will mount on 2g heads.

The only thing you can't do is use 93-99 CAS's on 91-92 heads beacuse they don't have the proper mounts.

[Blackmount]

can anyone send me a wiring diagram so I can make sure my wiring is correct?

[Blackmount]

I found it after I posted. Car feels a shit ton better I just set the CAS to the middle for now. Thanks guys, i will see how the car does when the motor is completely cool when i get up in the morning.
