Hydro carbons too high.
I bought a 1994 Z28 with an ATI procharger. The car had not been on the for 5 years. We replaced the cat and did a tune up. TThe car failed emissions for hydro carbons. We did a hi performance coil and plugs. Failed again at 1.7 (need 1 1 to pass pass]. We then puthe in 24lb Injectors and the stock ECU. Hydro carbons dropped to 1.5. CO was 4.3829 limit is 15.00.
NOX was at 1.253 with a limit of 3.00 . What else can I look at to get it down?

Would have been a lot better if you had just agreed to let me move your original post to this forum.

Re: Hydro carbons too high.
Whatever. We don't want duplicate post of the same topic on multiple forums. Causes confusion when a responder doesn't see what has already been discussed in the earlier thread.
I was only offering to help you.
