Thread: Car is acting up...Need some help guys. Please read...

So about a week ago I posted up about about getting a code pop up (p0705) that didn't make since. Here is the break down.

http://www.sr20-forum.com/general-sr20/47735-p0705-code-why.html

This is dealing with a 99 Nissan Sentra
Ve motor
Ve internals
Stock cat back
SSAC knock off
n60 Maf
Ve TB
Calum Basic Ve tune with n60 maf on p10 ecu

So along with that code I got p0400 which is EGR malfunction. Which the VE doesn't come with in case some people don't know about. Along with code p0136 which is rear o2 sensor. Now I know about switching the pins around which I plan on doing tomorrow.

Now the issue is... 2 times now the car has bogged. And then all of a sudden the codes don't read and the CEL goes off. Less than 40/50 miles later the P0136 comes back on. Then after that the P0400 comes on. I have checked the timing 2 times now and it's around 18/19*. Now when the a/c comes on... the car is a freaking slug. I don't know what else to do. I don't know why it is doing this out of no where. But didn't really start until the ecu went in. But I trust the ECU because it came from a very reliable source. So I know its not that.

But when it starts to bog out...the car kicks and jerks like its going out of gear and then catches up. So makes me wonder its the clutch.

Anyone have any idea what the hell is going on?

idk if this is thinking way outside the box, but how is your alternator?

Fine...13.7 Volts while running with a amp. And this was happening with out a sub running. It's a Ve alt from Miko that I got about 1 year ago or so.

I think I found out what my bogging at low rpm when cold problem is, the distributor cap and rotor are worn badly and my spark plugs have a really wide gap, have you checked them on your car?

Are you sure that the harness is connected GOOD at the ecu? I know that's a simple thing, that you'd always assume was good, but it would explain why you're having random issues.

As far as I know... but I can check it again tomorrow. While swapping pins out. I did go ahead and checked the spark plugs and they look almost brand new with no oil on them. And checked the timing again and it was a little off but I noticed that the distro is almost fully restarted but after being in timing mode the timing is at 18*

So far I swapped the rear o2 sensor pins to work with the 95-97 obdII ecu. But the p0136 code is still coming up. Looks like I have to swap over to a 3 wire rear o2 sensor. But the other 2 codes have not come up yet. I will drive it for a few days and see what happens.
