Red Top Beams cold start issue, im having a bit of a problem any ideas guys? Options

[1soljaslim5]

As far as exhaust set up i got the b pipe then the stock cat converter a resonator an 2 1/4 inch piping as far as the vaccum leak well maybe thats whats causing my low idle but then again im not sure but what i do know is that it still smells rich and the idle seem pretty low up until the engine is warm

[richee3]

Check your vac lines to see if they are hooked up and if so, what they are hooked up to. Did you get a new CTS?

I'm all for catalytic converters and lower emissions but that stock cat has to go. It's too old to be working efficiently and far too restrictive for the BEAMS. I hate exhaust systems on four cylinders but I severely underestimate how badly the BEAMS head needs to breathe. It made a HUGE difference when I replaced my exhaust. If you read my progress thread, I said over and over and over how rich my exhaust smelled. Replaced everything B pipe back and problem solved.

yes i did and still i had the same issues and i even reseted the ecu an CEL went back to normal no codes. as for the cat convert i have been trying to get it removed but many shops here in sac dont want to go through with it due to lawsuits and what not in other words they say (No we cant do it sorry) and as far as the hoses go there arent any slits or cuts to cause it however since i dont have the vsv you mentioned. from what i see im missing hoses and the only hose i have i see it connects from the charcoal canister to the the throttle. and there another hose that connects to the tps

just ordered the airbox so now i wait it out and im taking it to santa rosa next week my buddy has a friend whos willing to remove the cat so slow steady progress

[1soljaslim5]

bump

[Batman722]

why are you bumping ?
Do you have the stock airbox ? or the vsv you need ?
Still having issues after those are in ?

[1soljaslim5]

well i bumped just for my thread to get it looked at as far as airbox and vsv i am still waiting on them to arrive have not gotten them installed yet so far the idle is still real low did a tune up on her and now on coldstart it starts fine idles low for a bit and once warm stays at 1k tomorrow im heading out to santa rosa and get the cat removed so little by little.

[1soljaslim5]

So After long awaited weeks look what i got from UPS today Thank you So much Forgmann!!

The moment the package was delivered to my house i was so anxious i quickly opened the box to reveal its contents


got the VSV along with the hoses on connected to the vsv the charcoal canister and other from the vsv to the throttle only issue here is that its being squeezed by this container(still learning )

i also went ahead an got the plug extended


well got so excited quickly installed it here it is now wooooo lol


Still having that cold start issue car will idle high for a few seconds and then drop and stall once engine is warm however no problem with the OEM airbox i did notice its now super quiet like a Prius it responds better when accelerating no more bogging or jerking.
Once i floor it weeeeeeeeeeeee,
man....... it feels AWESOME!!i drove it out for a test drive and i must say im loving it.The Beams seems to want to continue pulling once you pass 7rpm and does not slow down i remember my 5s would pull hard but once in 3rd gear the fun was over . but anyways slow progress being made.

and here one more example how finicky the beams is.

Yet another testament to the OEM intake. You can read online 100,000 times about how much better it is than all the other intakes but you have to experience it to believe it. As for the VSV, the JDM Celica had give brake fluid reservoir on the other side of the car so it doesn't quite fit in our cars. I simply tucked mine underneath the intake area.

How does your PCV look? Any cracks in any hoses anywhere? How about the inside of the throttle body? I'm wondering if the idle issue isn't a result of a vacuum leak or possibly one of the air ducts clogged between the throttle body and ISCV.

Also, be sure to sign up here and ask these guys. Surely someone there has some relevant experience with a similar issue.

im trying to upload a vid of how it is now with the stock airbox but it seems photobucket mobile loads it up but once i go to the site on the cpu it doesnt show up? so ill try make another one or wait later see if it finally decides to show up.

Well im using all the parts that i bought from forgmann and all look in way better condition than my throttle hose and maf and hoses so yea its working a bit smoother but yea you're most definitely Right
you gotta try it out to believe it and i honestly can agree with everyone out there that said the stock air box is better now
lesson learned. as for making an account on mr2 forum ill get on it and see what info i can get.
much appreciated with all your help guys.

Heres a vid of how the car preforms with the oem airbox and warm engine (my phone sucks with the auto tilting and what not sorry best vid i could get)


As you can see the exhaust is now very quiet like a prius lol and the car now idles at about 700-750 which i would say is pretty normal

[Batman722]

I still think your IAC is dirty or going.
It's a common thing for our cars.

I didn't notice, what exhaust do you have ? Stock ? custom ?

[Bitter]

The issue is that the stock airbox likely has some special plastic fins and shapes that affect airflow past the airflow sensor, 7th gen GTS's have some fins that are needed and often omitted in aftermarket intakes. The solution is to cut the stock intake for the plastic section that's needed and stick it inline in the aftermarket intake.

Or it's simply a pipe diameter issue/sensor placement in the pipe. Again, that would be solved by reusing the OEM plastic sensor housing coupled into the aftermarket intake....if you want to cut up a stock intake.

i dont think that would be the case though ive read countless times that it is a common issue but i have a new IAC and as far as the exhaust goes i have a magnaflow exhaust wanted a more quiet stock look but with sound to show for it. im thinking about adjusting the idle screw and see if that helps tho it may not be the case.

[Batman722]

an entire magnaflow exhaust or just a muffler ?
What size diameter piping is the exhaust ?

[lagos]

During a cold start, two things need to happen.
1. The idle control valve needs to open pretty much all the way.
2. The car needs more fuel.

If you replaced the idle control valve, check the tubing going to it to make sure it is in no way kinked.

If the problem is with your car not getting enough fuel then either check for vac leaks between the MAF and the engine. Since the car is not MAP based, any little leak could make the ecu inject less fuel. If that checks out, inspect the coolant temp sensor and wiring, since that is what the ecu references to determine that a cold start is happening.

its just a magnaflow muffler the piping it self is 2 1/4 inch as for the exhaust its a bout 4 inches

[richee3]

It seems a little redundant but have you checked for codes again to see if anything else has popped up?
