Engine light on and sluggish running
I've checked the forum for a similar issue, but find variations of what's happening in my 2002 F250. My engine light started coming on a couple of weeks ago, and after checking with a mech. friend at church, and checking this forum I found out that I must have clogged injectors. I ran some injector cleaner through and it seemed to clear it up. Recently, the light has started coming back on. The light stays on for approx. five miles/minutes and then turns off. The engine runs sluggish, and by sluggish I mean it stutters on acceleration. Once the engine is warm, it seems to run fine. This happens primarily in the morning, but has also run sluggish in the afternoon on occasion. It's not exactly cold here in TEXAS, but the mornings have been cooler. Does it sound more like a glow plug, relay, problem than an injector issue?
