New to the group! Shoud have signed up ages ago lol. So I have a 1989 5.0 that has a pretty built motor that I bought about 4 months ago. Cleaned motor up and changed top end gaskets and all. Motor is stock bottom end with Brodix 5.0 heads, 1.6 RR, Trickflow Stage 1 cam, Track Heat intake with 1" spacer, Professional Products 75mm TB and EGR plate, 24lb injectors, Aeromotive fuel reg, black c&l 76mm pipe with a 76mm maf housing and 24lb sample tube. Was chasing a rough idle and bad backfire etc. Ended up replacing all of the ignition, tps sensor, maf sensor, new grounds to block. Car will start up sometimes ilding better then other times. On startup itll only idle up around 900 or so on a cold start. Idle doesnt sound bad but something still seems off and it doesnt seem mechanical, almost like bad readings from maf. Timing is set at 14 degrees and fuel pressure shows 38 with key on engine off and 40 at idle. Ive read a lot about how these C&L maf can fight you sometimes. Some say you can run a cone filter on the end (which is how I have it now) and some say that it has to have either the original air box or a cai through the fender to get it to run right. Has anyone had any prior experience with this before I order a cold air kit in hopes that it fixes it? Thanks in advanced!
