Okay Guys & Gals

I recently finished doing somewhat of a moderate tune up to my CT SC Cl-S 6spd w 92k on the clock. I changed out plugs, coil packs, IACV w/gasket, EGR valve w/gasket, oil change/filter, cleaned CT air filter and re-oiled, cleaned TB, changed wipers and got new battery. I have connected all sensors back, SC pulley tension is corrrect and IMRC/Actuator is working correctly.
For some reason I was getting the up and down idling and my code machine is telling me that is IACV. That issue was corrected with a reconnection of a vacuum line.

But now when I step on the gas in 6th gear I get a small hesitation/delay in response, normally it happens when RPM is b/w 2-3500. It does not do this in any other gear or above 3500RPM. Could it be that actuator is not adjusted correctly? Could be due to mixing 87 and 93 octane? yes! due to gas prices I do 50% of each

Any ideas? Please help

 

dont be cheap on gas especialy when you run supercharger... any codes ?

 

There is no CEL or codes. I only have a slight hesitation when i am in 6th gear around 2500RPM cruising at 60MPH and I step on the gas. It feels somewhat like a small delay and it lunges forward like when you hit VTEC. I dont hear any pinging/knocks. It does not seem to do it on any other gear. I was thinking may be the actuator cable is not adjusted correctly when I reinstall everything after removing old plugs.

 

The lower octane will affect performance, which is the opposite of what your doing with a supercharger not to mention probably lower MPGs. Have you calculated how much your saving by mixing the gas? Lets say its a 40 cent difference between the grades and your filling up 10 gallons every time. Your only saving 2 bucks a tank at most. If your that scrapped for money, you need to sell your supercharger.

 

First of all, I believe your logic of selling the charger does not make any sense at all. Two, even if I sold the charger the car still requires premium with the lowest octane being 91. Third, I average about 425-430miles per tank which turns out to be about +/-25.5-27 MPG. Iam not sure what CL do you fill up with 10 gallons. The CL has a 17.3 gallon tank. Most CL fill up with 14.5 to 16 gallons. Lastly, I am not scrapped for money or the correct term "strapped for cash". You are a young kid that has not even lived half of my life. I am well off and surely can afford to purchase all they toys that I have presently with out being in debt. BTW i was not asking for financial advise from a twenty yr old kid.

 

well, I fueled up this morning on my way to work with a full tank of 93 octane. I tested the 6th gear acceleration and did not feel the hesitation. I will test on my way home tonight to see if everything is back to normal. BTW, have always mix grades since 2003 with no issues in the pass. May be I just need to do 60/40 due to ethanol crap. I will post result later

 

Let me rephrase my calculation then, it's a 2 dollar difference per 10 gallons or 20 cents per gallon or 3.46 dollars per 17.3 gallon full tank (which is the capacity but to have that much, your tank will probably be bone dry). However you calculate it, my point is that the difference is minimal.
I understand that your well off and I see that you have a lot of good mods for your CL but the difference is not that big per gallon of gas. Lets say you drove 15k miles a year with a best of 27 MPG. It's a 111.11 dollar difference between using straight 93 and mixing per year. And we know you can afford that.

Now this is for everyone else considering running a lower then recommended octane: the difference is small! If gas was 1.00 per gallon, like it was 15 years ago, then the difference between regular and premium would have been 16.67% (assuming 20 cent per gallon difference for premium). Now that gas is 4.00 for regular, the difference has shrinked to 4.76% (same 20 cent extra for premium). Your car will run better and you'll have more power. There maybe a decrease in MPG if you run regular but I don't think it's proven yet.

 

... seriously you got an supercharger (that anyhow decreases MPG)for lets say (used one 2k, new one 4k) and you are still trying to save that 2 freaking dollars on the fill up ?? WTF are you nuts ? or jewish ? lol

 

The drive home was good. No hesitation or delay in acceleration while on 6th gear. Higher octane resolved the issue.

 

wait you mixed 87 and 91, why do that when you can just buy 89? I don't get it.

 

If you've been filling up this way for a while then it has to have just been a bad batch of gas. But I'd have to agree with AZNBOI, the difference in what you're saving is negligible. This does affect performance though whether its felt in the bucket of your seat or not. And if you're so well off then why are you mixing it in the first place? (rhetorical)

 

I normally would mix 87 and 93. Which is 90 octane and not 89.

 

Just because Iam well off does not mean I have to blow my money. I just like to save my money when I can. What is wrong with saving?

Why you'll dont take your car to the dealership to do repair work? Very simple, you most likely can do the work yourself and/or you dont want to pay the outrageous labor charges.

 

ok. Glad it's back to normal

 

So how does this work ?

1 Do you go in a pay twice ?
2 Give them a certin amount and tell them to reset the pump after your first half ?
3 Pay twice with your card at the pump ?
4 Put half in at one station and half at another ?

Just seams like too much hassle any other way but to choose and pump once.
Unless you like parking lot pimp'n at the pumps

 

I am not sure in what part of the country you are located, but here in TX we can pump our own gas and pay at the pump with ATM/Debit card and credit cards. So to answer your question = #3 and No to 1, 2 and 4.

Anyways issue was solved with higher octane and car is running great again.
