Hope I'm at the right place and hope this a'int to long winded. i am new to Jeep and the Wrangler forum. I have been given a 1989 Jeep Comanche Sportruck. It came to me stuck in second gear and with a soft clutch. i have since taken the tranny out (AX-5) and replaced a broken shift fork, rebuilt the master cylinder and replaced the slave cylinder. replaced a rear axle bearing and seals, replaced pinion seal (Dana35), both rear brake cables and brakes. working my way to under the hood, the engine idles rough. it has the 2.5l 4 cyl. my question is how do i tune this up? is there some sort of code reader for it? the engine tag says there is no adjustment for idle speed or timing settings. Also the truck also came with 235/75/15 tires. they seem way to big and makes the steering wander. i am going to replace the steering damper but am wondering what the stock tire size is? it didn't come with an owners manual. on the web i have found info that says anything from 195 to 235 /75/15.
i have read through some of the forums and there seems to be some pretty wise people here. so i hope you can help me, thanks
