would a bad connection on my CAI effect my throttle body? and cel?cel was on for 6 months thought it was my exhaust, other day i pulled the plug from cai and blew on it, two days later cel goes off and car feels better.

Before if i let second get to 4.5 then stomp it, it would just keep going. (like a civic)
Now after i let it get to 4.5 and stomp it and the whole front end lifts up and it takes off.

so would that sensor in the intake screw with the throttle body?, but i need a interceptor gauge for sure.

 

unmetered air will definately effect your car

 

you think thats what it was? cel on for 6 months, and this is the only thing i have done under my hood since it first went on.

 

A cel from a properly installed intake is normal as well...happens to me.

 

ok, well for sure thats what it is. It went on again so i pulled it out again and back in. 6hrs later when i went to work it went off. And car accelerated alot better and the engine wasn't as loud, and the intake whined again. I think it's affecting the throttle body. If it's gunna keep coming on and affecting my HP ima switch back to the stock intake.

anyone have a tip so my cai doesn;t make it go on and effect the hp.?

 

ever sense my intake install i'm having misfire problems,burnt plugs, and black smoke when i hit the gas. but no cel..i scanned it and the only thing that came up was engine misfire. but it didnt say what cylinder. i dont kno whats wrong or how to fix. so i'm kinda in the same whole as you.

 

Did you handle your maf sensor and get it dirty while installing it in the cai.
Try cleaning it with some contact clear that wont leave a residue.

 

i only handled the top peice where the wiring harness goes..i wiped the rest down with a microfiber cloth and blew into the inside..didnt help, but i dont think its the MAF because its not throwing a cel and when i scanned it only thing that came up was an engine misfire. there might be an air gap but i doubt it.

 

^
I heard if we misfire, it's 99% chance it's cylinder 1.

i think the firing order is 2-3-4-1.

 

anybody have probalyems with driving with their CAI in the rain???
j/w, dont wanna screw anything up

 

do you have a short ram or does it go into your bumper?

i havn't really noticed anything, i wouldn't go splashing or throwing any water. or driving threw puddles. if it's really damp and **** it could just bog the car down a bit, but really shouldn;t.

you should be good. just remember to not hit puddles or drive threw deep water,

 

how do you fix the misfire though??

 

I think the best thing to do is check your spark plugs. A misfire will mostly come from something that sparks the fuel or puts the fuel in. But i really don't think it would be your fuel injectors.

I heard not to put bosh in if you do change them. Put AC DElco, thats prolly what you have in them. They are GM Brand. I have to change mine today too.

I know our plugs are supposed to last something like 180 000 or some ****, but i have buddy;s changing them at 30 000, and im at 84000 but my engine light keeps coming on and the car seems sluggish.

oh ****, i never knew you were a SC, get NGK!!They cost $$ but you guys need them.

 

yeah it is the plugs but everytime i change them, they go AGAIN..literally the same day. i'm trying to find out how to stop that. when the plugs are good the cars good. but the plugs WONT stay good. thats the problem..

 

**** man, thats crazy.

even the really good NGK burn up?

maybe it's the connection to the plugs, maybe there is a short or it's giving it to much. I HAVE NO IDEA. lol.

take that back to the dealer (I know they have no idea about our cars) but they might just replace the whole system from plugs back to see if it fix's it.

 

i checked the autolites today and there all good. but i'm still getting misfires..i wire brushed the stock plugs and put them back in..still misfiring. i guess it looks like i have to switch back to stock intake,take off my neons and hope they dont find out i put royal purple in the car when i take it to the dealer.

 

hmm thats weird. does it back fire bad? whats it feel like?

do you think royal pruple would hurt that? pistons working too easy? lol. crazy, it's gotta be something. I hate car problems, frustrates me

 

it back fires pretty bad when i rev it..the car drives wonderful but sometimes you can feel the misfire. the misfire is constant..its every so often..but my gas is just going down the drain...its all going into the oil pan. if i didnt notice the misfire or the gas mileage going down i would absolutly love my car because it drives amazing.

 

tell me what happends at the dealer.

 

sure will..hopefully its nice this week because i have 4 neons and an intake to take off..i wanna bring it in before friday so i have it for the weekend but i have no clue how long them morons will take with it..i hate taking my car to dealers because they probably test drive the **** out of your car..but you gotta do what you gotta do..i'm not sure exactly what to tell them to check though..should i just tell them what its doing?

 

I think you guys might be looking at this all wrong. From the first post, it sounds like you installed a cai, and you either have a dirty maf sensor, or you are suffering the effects of an untuned maf table since your car is pulling more air. You can avoid the cel found when installing any intake simply by having your maf table and (to a degree) your ve table tuned with hp tuners.

I believe what is happening when a cai is installed is that the placement of the maf sensor is different, and it pulls more air differently from the stock air box, therefore the measurements it makes when fueling are different due to the difference in airflow. Our cars read heavily off the maf table, so at different rpms and map levels, you are going to be running richer/leaner, which could explain the misfires, plug fouling, etc.

Just a thought/opinion, so take it with a grain of salt.

 

k, well thats helpful for me. so whats my best option. check the maf sensor in the cai? i dunno if i have $$ for the tune.

i think the other guy thinks he was having problems from the cai, but i think it's more than that.

thnx for the help, any info is helpful

 

First thing I would do is clean the maf with maf sensor cleaner. The stuff I got is called "sensorkleen" I think.

Tuning, thats a whole 'nother ball game. To license your car on an hptuner interface costs $50 bucks per credit, and it takes two credits to license one car, then you're able to make as many changes as many times as you want. You just want to make sure the person that tunes you really knows what they are doing. So it kinda becomes a hard sell. You're car will run the best when its properly tuned, but most guys charge for it, so it would wind up costing ya unless you can find someone like me.

 

that maf sensor stuff expensive? i'll check that out tomorrow at canadian tire.

why?do you write tunes for 2.2's? if i tune it can i always put it back to stock?

 

It's cheap. It's not that much different from isopropyl alchohol in that it evaps real quick. Try checking autovalue instead if there is one by you.

And as for tuning, there is no tuning available for the 2.2's on hptuners unfortunately. I'm sorry i did not read earlier that you were a 2.2. There are some other options coming out for them, however they are only really worth it if you are doing a lot of mods.

So the tune may not be your issue at all, check your maf sensor and maybe clean the throttlebody with some tb cleaner, and we'll go from there.
