Almost ready to crash into a wall!!

It may be a non mass air car but you cant just change the injectors either. Speed Density is designed for 19lbs. Are you using 19lb injectors? The only other thing that I can think of off hand that will make the car load up like that is a bad map sensor. Can you get your hands on a code scanner? Maybe that can narrow the search a little.

I don't have a volt meter. I can get one tomarrow. I just pulled some codes. Koeo-34. koer-34, 42, 92. I changed all my vac. lines map has stong vac. grounds all look clean and secure. They were just reconected when I changed the intake gaskets (upper and lower) last week.

here are the codes

 

[toomanytoys]

Code 34 is the EGR valve voltage out of limit. 42 and 92 are rich conditions detected at the o2 sensors (left and right). Could be possible EGR failure? Maybe try disconnecting the EGR valve and see what happens? Have the o2 sensors been changed?

 

[cledusdtrucker]

new o2s new egr and it still does it unhooked i still think its the crapy inj

 

[toomanytoys]

Have you checked the plugs for fouling?

 

[cledusdtrucker]

i don't think he has maybe this weekend

 

[toomanytoys]

How many miles on the car? It is possible that there is one or two injectors that are dripping but that shouldnt cause the problem you are seeing. Are you sure the injectors are 19s?

 

[thrty5thsc]

No, I'm going to pull the plugs tomorrow before I go to work. I got a new map sensor on it too. I haven't used the nirtous yet. It's a brand new kit and the bottle is still empty. I'm trying to get it runnin good so I don't blow it up. I had this problem before it was installed.

 

[thrty5thsc]

Yes they are 19. Yellow.

 

[thrty5thsc]

It's either 173,000 or 273,00. I'm not sure if the motor has been touched or not. The guy I got it from said it was rebuilt 30,000 ago but who knows.

 

[toomanytoys]

Wow, with mileage that high new injectors couldnt hurt. Post back after you check the plugs.

 

[toomanytoys]

If the car otherwise runs good, doesnt burn oil,doesnt make any strange noises and has good oil pressure at idle then dont worry about it.

 

[thrty5thsc]

Yeah it's up there. It's stong though. I left my friend on 690 tonight. He was driving his kids 350z 6sp. He said he had it to the floor too.

 

[thrty5thsc]

It stalls at red lights sometimes.

 

[toomanytoys]

You should also bump that timing a little bit. 10 deg is where the factory set it. You could probably go as high as 14. It makes a big difference. Get rid of the stock airbox if it is still there.

 

[thrty5thsc]

Yeah that's gone. K&n in the factory box. I set the timing at 10 for nitrous. that's where the zex instuctions said it should be.

 

[toomanytoys]

The K&N is a good move. Is the air silencer in the fender still there? Get it out if it is. As far as the timing goes, when the funds allow get yourself a timing retard like the ones from NOS, Jacobs, MSD etc. They will let you run more initial timing on the street for better power and they pull timing out when you hit the spray. Its the best of both worlds.

 

[thrty5thsc]

I took the box in the fender out but I still have the filter box.

Opps sorry about that guys, always forget about the no MAF equipped cars. I still sya it's an injector problem. Did you disconnect the battery and let it sit to reset the computer. I ran 14 degrees and 2 degrees colder plugs on a 125 shot for years no problems. How big a shot are you running? Anything over 50 I think you need bigger injectors, larger fuel pump and a tune.IMHO

 

[thrty5thsc]

it's set at 75. I have never used it.
