A little background:

I just got doing a head swap on my 2000 dx hatchback to make it sohc vtec, instead of sohc non-vtec. I also put the edelbrock complete turbo kit on at the same time.

Problem:

When it was all said and done, I am pulling a couple of codes. 3, 23, and 45, which is, if im not mistaken, Map sensor is getting a high input, Knock sensor problem ( I don't have a knock sensor ), and I'm running rich or lean. Decided I've done enough to this car, I wanted to figure out what was wrong with it, and have someone else do the work, I took it into a local shop. They told me my timing was off by a lot. They set there gun to 16 or something and i saw that it was off. But the said I had to get an ajustable cam gear to fix the problem, can't I just adjust the distributer? Will this fix the problem? Help!

Symptoms:

1. Car stumble upon acceleration and idle on start-up.
2. Car backfires when given a lot of gas.
3. Car actually wouldn't let me give it gas on the highway when was pretty fast it eventually would die down everytime i tried to give it gas. I had to turn the car off and restart it and the problem was fixed. Wierded out!

*I checked my spark plugs, they look pretty red believe it or not. and had just a little black around the rim. ( not oil )

bump

 

bump anyone!?

 

ttt

 

I'm not too familiar with boost, so I cannot do too much but.....Why do you not have a knock sensor? Unless you are running a program that eliminates it, it will throw a code etc. As for [ignition] timing, yes, you can set it with the distributer. Where is your MAP sensor located? I do believe that boost will affect its readings if not placed properly, correct? Someone more familiar with boost needs to chime in....

 

Damn that sucks that is why you do one thing at a time. good luck

I'm pulling a code for the knock sensor. . . .

 

y8s have knock sensors. I think he is running a y8 ecu. I would just change over to obd I ecu with uberdata. Also with timing go by yourself a timing light and jump the connector and check your timing. Usually if your timing is off by a tooth your car won't even start, and if it does you will have a hard time running it. I think they are feeding you BS. Just adjust the timing with a dizzy.

 

hey man.. runing boost will cause u some trouble with the intake u need a missing link to fool the computer to not read boost and check you timing make sure u got the right timming belt also,, it would help u alot if u got a jumper and went to obd1.. u can use a 92-95 vtec computer witch is a p-28.. it will get read of some of your sensors and make it run a lot smoother,, if it still runs a little like it;'s falling own it;s face then u are not getting enough fuel in boost, get a gauge and watch and see what it does mine was rich before vtec with a gsr computer at vtec it would start to lean at boost it would fall own it;s face,, i need more fuel.. hope this helps.. if u need any thing let me no....
ps air to fuel gagues will help..

 

air fuel gauge is a piece of ****.... need wideband if you wonna test that.

I adjusted the dizzy and fixed my timing, and it just idles higher or lower accordinglly. It still has all of the symptoms described in the first post though.

However! I just got another code reading an iacv fault. Could the signs above be early signs of a bad iac valve? is therhe a way to clean it or anything, to delay the process of buying a new one?

Thank you, i forgot to mention the shop also suggested this. Anymore suggestions?

 

take of the iacv

clean it off

ohm it out (it's a solenoid) see if it's good.

 

you never mentioned.. what kind of fuel management are you using?

obd-2 cars tend to be VERY picky towards any changes. I would get a obd2b-obd1 harness, use a p28 and run uberdata. or alteast the AFC w. 450cc injectors.

 

Alright, will do, keep posted though see if this doest fix my problems!

With the Turbo kit itcomes with a turbo link management system.

 

I talked to a technician who noticified me that it was my map sensor and that this was a common problem with the edelbrock turbo kits. I'm just gonna have to buy on and keep my fingers crossed i guess.
