Need Some Help Please CPU/AFR Problem

[1993 Sleeper Z]

Alright...
I just recently added some bolt ons and now I am experiencing some problems. First I guess I need to give you a list of bolt ons so here it is:
BBK Headers, BBK 58mm Throttle Body, BBK Power Pullies, SLP Cold Air Intake, Ported and Polished Intake Manifold, MSD 8.5mm Plug Wires, and I also had new plugs put in but not sure what kind.

Now the problem...

I only drive the car 10 miles every 2 weeks. So, when I start it up it will run great at idle. I can drive it 2 miles down the road and it will still run great at all RPM ranges. When my engine starts to warm up it is steadily warms up until it almost overheats and then my fans kick in. This is due to a fan problem I had earlier and both of my fans are wired together so they kick on just before it overheats. So once the fans kick on it will cool off very quickly. The fans kick off again and it begins to overheat again. This time it starts to bog down like it is running way too lean and my RPMs will bounce around while idleing. At this point I shut the car off and I have to wait for it to cool down and then I can start it up again and it will run fine.

I'm guessing it has something to due with not getting enough fuel when it is hot...but I'm not the mechanic and that is why I come to you all. Any solutions...?

Thanks again everyone!

Edit: Don't forget it's a 93 so it has speed controlled A/F Ratio

I'm not too sure about your bogging problem, but I do know that the stock fan settings are for 226 degrees I believe. If that's not the exact temp, then it is something very close to that. The fans will basically kick on right as your water temp starts to near the red.

Can a hot motor prevent enough fuel from getting to the motor?

Not sure, but I think I remember reading on here somewhere that high engine temps will cause something to retard the timing. (??) Maybe an aftermarket fan switch to kick the fans on sooner will help. I'm far from an expert tho, so take everything I say with a grain of salt (and if someone could explain that phrase to me... makes no sense... )

I dont think that my fans are working right now , so I need to find a way to fix that.

Thanks for the info 96Camaro, but I don't think that has anything to do with this thread...

Ok, first off, get your PCM tuned. While a dyno-tune would be best, even a mail-order tune will be better than nothing. You can have the fans tuned to turn on at 180 like I have (I've got a 93 as well). You'll pay extra since the 93 uses a replaceable chip vs. a flashable one. Also, have you done the throttle body coolant bypass? How many miles do you have on your car?

As for your post 96Camaro, don't hijack someone's thread. Start your own and state your problem.

Thanks Steve, I'm new to the forums so I hadn't ever heard of the throttle body bypass, but now i've read up on it and it seems like it may really help me. Could the bigger throttle body be getting hotter than a stock one or should it just help out about the same. I figure it's getting a lot more air now, but i assume the problem is it's getting a lot more hot air. Let me know if i'm wrong about this. Also, is there anything I could do to get any kind of cool liquid/coolant through the throttle body or would it be pointless for my $?

Your bigger TB at this point may be overkill. A stock one, or even a ported stock TB, with an airfoil would probably work better than your current TB.

As for putting a cool liquid through your TB...it's just honestly not worth it. It would also be a lot of hard work that would have a bunch of custom fab, and would cost a good amount of green. If you ever did manage to set it up, the gains in the end wouldn't even be worth it.

Just by disconnecting the coolant lines alone is what you see better gains from...that's more than adequate.

Exactly what he said. The coolant bypass will make a noticeable difference. And, as I said, definitely get a new chip for your car to accommodate for the mods. I've got one from Alvin at PCMForLess.com and am pretty pleased. Very good customer service and will retune your car for free if he's off (e.g. take it to the dyno and its too lean, like with me). Hope this helps.

160-180* tstat and a low temp fan switch. just be prepared to be without hot hot air in the winter. 160 blows luke warm. 180 is the best for a combo car

Thanks a lot guys, you've really helped me through this one, now all I need to do is get home to my baby and get her fixed up. As for the winter...that's not a problem cause the car is garaged til next spring already cause I'm at school and it's not worth paying insurance when I only drive it 20 miles every 4 weeks. That way I don't break anything, too. I will post another forum if I have any new problems in a couple of weeks.
