Put my chip back now RPM jump and CEL on

Hey guys, last January 2013 I took my chip off , it's a DP Tuner with 5 settings. 1 - stock , 2 High idle warm up, 3- 60hp economy, 4- 80hp and 5 - 100hp or 120hp.

It's 1996 Powerstroke 5speed 4x4.

Anyways, after I unhooked the batteries and removed it off my PCM I hooked the batteries back up and drove it around with the chip off till sunday July 28th I think? Anyways, when I put it back on I unhooked the batteries, pulled out the PCM, slid the chip back on and installed the PCM then hooked up the batteries. Chip lit up, all 5 stages worked and left it at that. Drove it tuesday July 30 (very hard start and white smoke came out, took longer than normal to turn over) and after a few minutes and a couple blocks my RPMs started fluctuating and the CEL came on. So I pulled over since I was at my doctors office by this point anyways and turned my truck off. Came back to it 30min later and started it. Everything seemed fine, CEL was off and I put my chip back to stage 1. I forgot to mention that the RPMs were jumping around on stage 3. Drove the truck for the rest of the day on 1 (stock) and no issues. Wednesday the 31st was also a hard start, longer than normal to turn over and white smoke. August 1st truck started great as well as today but at one point yesterday I had little surging driving in gear as if my IPR was acting up like it did in Nov of 2012 and I had new one installed. Today Aug 2nd I was curious how the chip would act again so I turned it up to stage 3 and drove fine. Or so I thought. After about 5minutes my RPM's were all over the place so I stopped my truck and put the chip to 1-stock, monitored it in neutral and they jumped up to almost 2000rpm and CEL came on. Turned my truck off for about 15sec, started it up again. Rpm's jumping a bit so I just turned it off for about 1hr, came back to it CEL off and drove home no issues on stage 1. Gonna remove my chip I think and just not deal with it anymore. PCM issue? Injectors? Or is the chip just ****ed haha. I never had issues with it when it was on the truck before though from Sept 2012 to January 2013 DP Tuner. Or did I remove it improperly or install it improperly?

Def. remove the chip and re-test. If it runs normally without the chip, it's NOT a PCM issue, it's the chip. It's possible that it's not seated properly, but you took the right precaution of disconnecting the batteries.

Sorry bout the grammar above lol, half corked and feeling great! I didn't think it was a PCM issue. When I took the chip off, I put it in my glove box. Now im wondering if the connection points are dirty. Should I spray them with an electrical cleaner point spray? As for the chip, im not scared to spray it with an electrical cleaner but the PCM I am. If the chip is screwed up, I honestly couldnt care, it came with the truck when I bought it. My fuel milage was always better without it and im not a power hungry guy. I always preferred reliabiilty over power anyways.
