My '93 SE begins acting erraticaly (stalling) 5 minutes after cranking on cold mornings (it only lasts a couple of minutes, then back to normal). I've only had the car 2 months. Up until now everything has been fine. I changed the air filter, fuel filter and spark plugs about two weeks ago because it was skipping a little (it seemed to correct the problem). The stalling problem started four days ago. If you hold the excelerator in one place while it's stalling, it pulses (the pulses are about a second apart). It died completely once, but restarted with no trouble and ran normally. It has done it once (slightly) in the afternoon in warmer weather. After reading other threads I'm guessing the MAF. Any suggestions?
