89 engine runs real rough, ECM/MAF??
Any help in identifying the root of my problem.
89 vette sat for 3 years. Drained old gas, new filter and pump. Car starts, will idle at 600-800rpm but very rough, when I step on the gas it idles down to a stall. Overly loud sound of air rushing/being sucked into the engine. Checked all hoses and they are good.
Could this be the ECM or the MAF???
Any help is appreciated.
