New block, 2.3 stroker with bad issues

[DeadsEvolution1]

Ok so if I can't fix this in the next week I'm selling this POS or blowing it the hell up.

Car will not idle. If it does idle it's at 500rpms and rough as hell. Also it will barely rev up past 3k at all. Thats nearly flooring it down to get it to rev up. Also it sounds like crap. If I hold it at 1500rpm's it sounds bad. Like it's missing or something. It's almost spuddering.

Thoughts on this:
1. Injectors are failing?
2. Not enough fuel getting in
3. 1 cylinder not firing
4. Timing off somehow although redone 3 times.
5. CAS way off (I adjusted it alot but not with a timing gun but still no help even If i set up the CAS way off it still idled terrible.)
6. TPS sensor off?
7. Could the Knock sensor cause any issues?
8. 02 sensor broken?
9. Any chance a fuse or something is blown causing issues??

Anyone and everyone please give me some insight. I am on tilt right now done with this f king car. Thanks

change your air flow sensor.if that doesnt do it its your computer.

get dsmlink!

What makes you suggest the MAF? Just curious?

All these sensory / ignition issues, off a hunch I'd try a known working ecu.

because if you disconect the air flow sensor.it will do exactly what you described

 

[DeadsEvolution1]

Ok I'll give that a shot tomorrow. And the ECU thing, I was actually thinking it was that from the get go. So i'll try both. I have a spare CAS laying around I am going to put on and a spare TPS that I will put on tomorrow.

I can give you a video of my car with the AFM unplugged idling and starting up like there was one plugged in.

It's best to do 1 thing at a time I've never seen a CAS, fail but there is always that one that happened to be not working, but it's highly unlikely to be the problem given the connection is 100%.

You can try this turn the key to on have the sensor plugged into the harness and rotate the key(of the CAS) with your hand you should hear the fuel pump and the injectors actuate.

Actually when I was turning the CAS with my hand i always heard a noise when it hit a certain point. So would that rule out the CAS?

Also can you post a video? That would be awesome

I pulled the spark plugs today. The spark plugs from cylinders from 123 are white, and the spark plug from cylinder 4 is black. Too much fuel? Or that spark plug isn't sparking? My car is smoking so I assume it's too much fuel correct?
