Default TR224 installed, Questions!!

I installed a TR224/224 112 on Monday. The car is untuned.

As expected when the car was first started it took a minute to sort itself out and come to a consistant idle. It threw an SES light after driving it but that disappeared today <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> But here is what it is doing since then.

-When it is started from a cold start (ex overnight) it now seems to start right up and idle fine.

-When it is started warm or even within a few hours of it previously running the revs fluctuate between 400-1000 and it almost wants to die for the first 15 seconds or so.

-Once the idle smoothes itself out and it is driven, for the first few minutes if I come to a stop or bring it out of gear the rpms drop and fluctuate between 400 and 1000 like when it was started. This goes away after a few minutes though.

-I know the car is running rich because I can smell gas.

I can't get it tuned yet ($$). Will the computer sort some of this out or will drilling the throttle body out help?

Other than that the car is running good. Sounds awesome and pulls great. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Drilling out the throttlebody will fix all the symptoms you listed.

Like JMX said drilling the TB should fix most of those problems up. If you have a scanner just drill the hole out larger until you get you IAC counts between 30-40.

Mine did that also. After driving it about 50 miles the PCM seemed to figure out the idle. Now it just hunts for idle a little after a cold start for a few minutes. The computer needs time to adjust doesn't it?

My 224 did this as well, I drilled out the throttlebody and it did improve some, I need a tune to really get it under control I think. Once I get heads on I'll go for the tune, until then I can live with it after the throttlebody drill. It surges sometimes but never dies even with the AC on.
