I m looking to buy this 98 4x4 and the gauges with the key on go to 120 mph and then to zero and the tach does the same thing along with all of the lights in the dash for warnings like ABS check gauges and etc. Going on and off while it is idling Also it wont start ,it will if u open the throttle up a little and hold it open to run at 2grand for a minute and and then it will idle rough.I should say that it is not able to to drive and it was running fine the other day no hiccups at all. I have a 96 ram 1500 so I m no stranger to Mopar but all of my diagnostic stuff in another state due to moving so I would love to have some input from you guys.the forum helped me with my Intrepid cooling stuff. THANK-YOU

OK I m not worried about the engine running I m wanting to get the electrical fixed

Thank-you for reading and brain storming

 

How many miles does it have? What type of engine does it have? How much do they want for it. From what you say the issues already are I'd say 3,500 to 4,500

 

oh its not the price it is the item to fix it could it be a ground or a CTM and it has a 318 with 130000 miles but in great shape and i can fix anything on it if i can figure out which direction to start
You see wife has stage four cancer and money is tight i dont want to throw alot of money to figure it out so if it is a ground or a CTM or PCM

 

the no start and rough idle could be a bad IAC valve my 3.9(basically the same just 2 less cylinders) had the same sympotoms and cleaning the IAC fixed it the rest idk tho maybe a loose connection

 

yea but all of this started at the same time all at once

 

the IAC is not that expensive or hard to do iw ould suggest that he owner do it before i bought it and if that fixed that part of the prob then look into maybe getting it and fixing the rest
