first off, hi everyone. secondly I recently started upgrading my '02 Accord LX 2.3 4cyl 4dr. auto. and just looking for any info ,ideas and resources. ALSO i recently put a AEM cold air intake on it and sometimes when I let it wind out the rpms before it shifts (near redline) it makes a small back fire noise. take into credit iam new to the world of Honda iam used to working wth big block fords so iam kinda at a loss sometimes trying to figure this thing out
