- Sun May 30, 2010 2:55 am #197701 hey guys, can anyone help me with my car?

I started it this morning and it was fine. Started it again later on the morning and the revs were high, as usual (choke)..
then as temperature rose as normal, the revs were still high as if choke was still on. this is at about 2.5k rpm.

the whole way it was like this.

and the revs wont let me get any higher than 3.7k rpm, it would cut out as if it was red lining. i also noticed that there was hardly any power. so i got home and opened the bonnet and saw some smoke around the outsides of the engine, this couldn't have been overheating because my temperature was perfectly fine. my friend suggested that it could be a sensor?

does anyone have any ideas?

please help a brother out haha

cheers guys! have a great day!

- Sun May 30, 2010 6:41 am #197758 your timing could be off by a tooth when it is the ecu will go into safe mode and wont you rev higher than 3.5 or 3.7 it will also idol real fucked up sometimes high of sometimes low. if its not your timing or ecu check your distributer. then again if you distributer is off that means you timing is off

- Sun May 30, 2010 6:43 am #197759 oh what engine do you have

- Sun May 30, 2010 7:35 am #197770 it's a d15b sohc vtec 1.5

- Sun May 30, 2010 9:04 am #197771 yah just check all that out im sure its the timing tho cause it happened to my boys h22a it took me about a week and 3 different ecu's to find out it was the timing

- Sun May 30, 2010 10:50 am #197774 oh really? oh alright so not any sensors then?
i wonder where the smoke was coming from

- Sun May 30, 2010 7:49 pm #197841 idk are you leaking oil thru your head gasket

- Mon May 31, 2010 1:18 am #197862 Do you have a check engine light? If so, read that and it will tell you what's wrong.

Timing belt off by one tooth won't necessarily do that. I did a head gasket on a B16A3 a while back and the intake cam was one tooth off. Still ran and wrapped all the way out to redline. Same deal on the single cam.

- Mon May 31, 2010 4:10 am #197882 My car does the same thing.

It'll idle up and down as if someone's holding the gas.

But when I warm the car up and get the temp up the car won't idle.

I'm thing it's my air idle control.

Anyone have any ideas?

- Mon May 31, 2010 4:38 am #197885 That's what I've been thiknking it was. My brother seems to think different.

- Mon May 31, 2010 4:54 am #197888 its deff your iacv if you disconnect the sencor it will stop but dont leave it like that it will only get worse just do it temp till you get it fixed

- Mon May 31, 2010 5:04 am #197889 Okay, thanks for the help.

- Mon May 31, 2010 10:01 am #197924 tekdya the sensor should read 4 meaning when you test it the check engine light will blink 4 times then stay on for a few seconds then repeat the code again
