My typhoon started surging today, While driving around 30-40 mph the tack would rise up and down about between 1000-1500 rpm when I was off the throttle.As well at the stoplight when I was waitng for the light to turn green.The rpm stayed at 1000-1100 rpm and it felt like it wanted to creep forward.I really had to apply the brake to keep it from moving forward.When i got it home and put it into park , the rpm stayed high at 1000-1100 for about 1 minute beforte it came back down again to 600 rpm at idle. The truck is 100% stock and original.It has 26000 miles on it. Any suggestions for things to try to get it back to running normal again?
thanks,
janeto

Re: surging issues

do you have a datamaster?
Could be a number of things. Iac would be my first guess. I had low voltage that did that too. Could be the alt going bad. Vac leak too.

:werd: For me, it was voltage. Could be all those factors though.

Re: surging issues

I have a similar prob in the SY. The rpm's rise/fall at idle about 5 times and then it is fine. It only happens when I get off the gas. It seems to run fine though. I am still clueless??? Any ideas???
