i had a similar problem on the s14 Sr. changed the fuel pump. changed the MAF. made sure that all sensors are connected as well. it turns out that the MAF pig tail had a little tension. harness could have been broken. but since the S14 SR MAF are not interchangeable due to the part numbers. i notice the wires by the MAF plug were exposed. i disconnect the MAF and it ran and idle perfect. but putting the MAF on it ran like shit. so i had my brother fixed the pigtail and cover the exposed area due to tension. it ran like if were brand new. but you have to make sure that all harness plugs were connected properly. and yes people with the S14 SR you must buy another MAF with the same part number as the existing one. unless you tune your ECU for the Z32 MAF.
