ok i recently bought a 383 iroc with a mini ram on it it also has a zz 383 cam in it with 1.6 roller rockers. well the problem is the car has the idle surging i already cleaned the iac sensor and replaced the spark plugs and its the same. i also adjusted the tps to 52 and the the fuel pressure is at ideal. i have thrown a maf code once while driving and it disappears after the car has been restarted. im killing myself for this please help also its and 88 thanks everyone

 

You have a couple of items that need to be tuned in for that setup. What are you using for data logging and chip burning? Which MAF code is it?
