bansheebarnes Posted June 5, 2009 Report Share Posted June 5, 2009 ive had a 1994 dodge ram short box reg cab for over a year now. it is a automatic trans. with 4x4. the engine is a 5.9 or 360ci. its fuel injected. the truck itself has 228k miles on it. but in surprisingly good shape. the transmission was replaced at 130k. when i bought the truck it had the problem....we put a new fuel pump in it ( it was going out) and we hoped this would solve it...but it didnt and i have been living with it for a year. the problem: when i let off of the gas the rpm's dive down very low, and sometimes dies. i discovered when i rev the gas quick it goes back to idle smooth. at highway speeds the problem is not noticeable because you're going fast the engine doesn't go back to idle. i can live with it just having to rev it when going really slow. but for parallel parking i always think im going to hit a car. and due to the fact i have duel cherry bomb exhaust i look like a douche bag revving my engine every time i go slow in town (tight traffic). what could be casuing the rpms to drop like that? but not do it when i let of the trottle fast. any suggestions would be appreciated. thanks Quote Link to comment Share on other sites More sharing options...
assbandit Posted June 5, 2009 Report Share Posted June 5, 2009 (edited) I have a 99 ram 1500 with a 360. When i bought my truck it was doing the same thing it wouldn't stay running unless i was on the gas. I thought it was something major. I went to walmart and bought a new battery and i haven't had a problem since. Trust me and get a good battery!!! you'll be surprized Edited June 5, 2009 by assbandit Quote Link to comment Share on other sites More sharing options...
flyhighprerunner Posted June 5, 2009 Report Share Posted June 5, 2009 Have your battery tested before you buy a new one, also check your air filter... Quote Link to comment Share on other sites More sharing options...
bansheebarnes Posted June 11, 2009 Author Report Share Posted June 11, 2009 Have your battery tested before you buy a new one, also check your air filter... i had a new air filter put in when i bought it. and the batter was replaced less than 6 months ago.
