Maybe you are having a thermostat issue, Check to see if it is opening and closing. It may be stuck or you may have a blockage somewhere.

K..I'll look there as well, thank-you....other than those two things the car sounds like a rape ape:rock: I will try and figure out how to upload a video, maybe put the video on YouTube and just post the link

Yea if you did not bleed the coolant correctly and thoroughly, you will get air pockets and it will have hot spots.

As far as the scanner not reading, what year is the car?

Its a 97' so its OBDII. The problem is I don't know if it was scanable prior to all the work being done.

Check to see if your cig lighter works. That circuit also feeds power to the obd2 port.

Thanks bmx I get out of work at 3 so I will check those few things, I was wondering I placed the front two O2 sensors in y-pipe, would that cause a check engine light to come on, seeing that they are not in the collectors?

Hey bmx totality off topic but a few weeks ago your car was w/o its hood and had a clear tarp on it, what was up with it?

Also check your ecu fuses.
You may need to use a higher end code reader like a snap-on or even a laptop with the code reading software.

Are ecu fuses under the hood or on the driver side door console?

Should be above the driver side kick panel , and maybe a small fuse box under the hood.

The fuse box should be labeled or the cover will have the layout of the fuses

Been working on painting the hood, finally got it on and got my trans back in. Few more things to do and hopefully go rippin around the road again. Having the o2's in the y pipe shouldn't be causing your CEL. It would have had to entered closed loop operation for the computer to even start using them. That takes a little bit of run time though.

If youknow someone with one of those fancy snapon scanners with the touch screen and all that, then you might be able to get the codes. the cheaper simple code readers dont always work, especially when you have a major engine mod like yours

Uh, not to be a ass, but how exactly does the complexity of the engine change the stock sensors and their read outs to the PCM?

A code will show on a basic reader, the advantage to the fancy snap on real time scanners is the ability to check each sensors output, but that hinges on the user realizing these values and being able to make sense of them.

I have had instances where the cheap scanners didnt pick up anything, and the higher end scanners worked fine. The snap on scanner would help show if there are any snesors unplugged or not working. With his major mod to the engine it would be a good idea to get a real time scanner hooked up to make sure everything is in order, and to help find any weak links with the sensors.

Fair enough, never really used a cheap scanner.

I have and they give little to no information. It is like working with an OBD-1 when using a cheap scanner

Ill get it figured out, I have been so busy at my PD, I don't have time right now to start getting into it

Update on my project, I got the heat issue fixed, turned out to be just air in the line. The car actually runs pretty cold, 180*. Still have my check engine light. I checked all wires and fuses and my buddies scanner is not picking up the car. So went ahead and checked an older GM car unreadable also. Strange ...but this leading me to believe its the scanner. Odd thing is my dd driver is an 03 aveo, reads it without any problems. Next issue is my new Hurst short throw shifter ....its a nightmare trying to get the car in reverse anyone know what gives? Also I'm looking into an exhaust system thinking about borla but anyone running long tube headers without cats. into a nice cat. back system that doesn't kill the sound of motor. The car has a really wicked cam to it but right now it sounds like I'm standing next to a modified nascar.

I'm selling a b&m if u dont like the hurst. No problems getting into reverse, or any gear for that matter

Elaborate on "nightmare". Did you plug in the lock out solenoid?

I was thinking the same thing. Are you trying to force it into reverse with the engine off, too?

By nightmare I mean every time I think I have just put the car into reverse its really in 6th gear. Don't get me wrong I can get the car in reverse but it is nothing like the stock shifter.

Make sure the solenoid works and is plugged in.

Good news everyone my problem turned out to be the scanner, put another scanner to it cleared the codes and no CEL. I have a few videos of the car anyone know on how I can get them off my phone and onto here.
