A high idle speed can be caused by a poor connection at the Throttle Position Sensor (TPS). Connector replacement kits are available from Mazda dealers and possibly some Ford dealers.

1998 Mazda B2500 Problems
Rough Running Idle, Erratic Speedometer Operation, ABS Light Illuminated, Check Engine Light, and Automatic Transmission Shifting Problems
Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.
A dirty, or contaminated mass airflow (MAF) sensor can cause the engine to run poorly. There may be a Check Engine Light with trouble codes relating to the MAF sensor. In some cases, carefully cleaning the sensor element will fix the problem, but replacement may be required.
The engine may fail to start due to an electrically shorted sensor. Some of the sensors may internally short and not blow any fuses. A technician may find no spark and no operation of the fuel injectors in the diagnosis. One way a technician may isolate the defective sensor is by disconnecting sensors one by one to see if the engine starts.

1998 Mazda B2500 Reviews
I had a 1995 Mazda B2000 that my brother gave me,, and drove basically around the United States,,had almost 300,000 on it when I was pulling into Oklahoma City, from Detroit. 5 miles out of town, hit a 10 point buck that ran in front of it and totaled it! now, I am am a city guy. this is the bible belt, the hood flew up. I stuck my head out the window to steer in HEAVY traffic, and managed to pull over. behind me me, were some concerned (bible belt) citizens, and stopped to check up on me, as they had seen what happened.. when I started saying wtf, u got to be f$^kin kidding me! hell no!!! they briefly got the words out of their mouth "are you alright?" when they turned around, got back in their car, and locked the doors! lmao!
I told you that story, to tell you this one,,
I have a job that makes me drive about 30 miles a day(15 each way).. and blew up a 2005 chevy malibu,blew the head gasket, had a ford 2004 ford windstar die (unkown problem),, then bought a 1998 Mazda B2500 with rust around the back wheel wells, 5 speed manual,4 cyl,nothing special. my gas payment is about 50 bucks every 2-3 weeks! can't be happier, I just need the rear wheel-wells fixed, the air conditioner relay needs to be replaced,(cheap) I have a fiberglass bed cover, that has warped some,and the pneumatic lifters for the cover are shot! and the lock is broke,, prob $200.00 bucks just for that! so I will apply that to a Gem-Top!
bought my truck used with 165k miles on it. had it since 2005. only major thing ive had to do to it was replace the clutch. doing the regular maintance like oil change and etc..... been to pa nc tx just all over the us. it has 350000 miles on it now and iam still not scared to get in it now and head out on a long trip. great truck
I can't complain. I bought it new in 1998. Has served me well, I am replacing the starter, the only major problem I have had. My Bmw transmission just went out so I am back to my trusty truck again.
My first pickup ever, and after 188,000 miles I can say it's decent. You'll want stronger shocks than the OEM ones--try Bilsteins. Ride has always been stiff. Strong engine, nice interior, still mid-20's mpg. Had new clutch at 165,000--also broke 1 sway bar link in suspension. New lower ball joints at 185,000. Not all that bad for 11 year old truck with such high miles.
