i have a 98 svt and the other day i get in it an start it and the revs keep jumping to 2000 an back down to 250 finally it settles at around 400 rpm then i take off and soon as i let out of the gas the motor cuts off. the only problem is its intermittent. today it works fine. some trouble with it yesterday. i think its the iac possibly some junk stuck in it. the maf, and tps all check out. just wondering if anyone else had a similiar problem before
