I have an Idle Speed Actuator (ISA) on the throttle body. 86 and 87 look like they are the same according to the pictures on Kragen.com. I don't see any resistors for said motor (actuator) in the engine bay nor in the wiring diagrams I have. I don't have any other symptoms. I think the...

I ran some fuel cleaner twice through the fuel system with no improvement. I was thinking that the injector was bad and not the throttle body.

Anyone?

1986 2.5L throttle body injection Jeep Cherokee. The Jeep has had trouble starting in the mornings. Now it doesn't want to start at all. I have to crank it multiple times before it will even consider starting. I found that fuel isn't being sprayed during cranking The butterfly in the...

Okay, I have an '86 2.5L and I am wondering if anyone has bored out their 80's throttle body. I want to know how it effects everyday driving, performance and fuel ecconomy.

Anyone ever bore out their throttle body? I'm more interested in engines with throttle body injection. How did it perform? Any drivability issues? Anything else done at the same time of throttle body?

Kragen shows the MAP sensor is the same for '86 2.5L and '87 4.0L. I don't know how long they used the sensor.

I read that exhaust wrap is very bad because it holds in the heat and causes the manifold to burn up or rust from the inside out. That's why manufacturers won't warrantee their headers if you use the stuff.

The word I got from one of the guys at Banks was that Jeep manifolds crack because their exhaust runs too hot. I don't have a solution as of yet. I used the 4.0L as an example for where I might get the O2 sensor placed. Do you still have the stock fan clutch setup? If so, lose it!!!!! I...

Here was my idea from Banks' Jeep stuff. Modify the exhaust manifold to work with the EGR tube and then use their head pipe, http://store.bankspower.com/Categories.aspx?Category=fa2d06e6-54c0-4f13-ac80-a5177c59d9ce#, because it has provisions for the O2 sensor and it would reduce the cost of...

Anyone ever have this problem or is it just me and tweakado?

My motor mounts, trans mount, and exhaust hanger are all good. I've even gone so far as to make a bracket that mounts to the trans and hold onto the exhaust pipe. I'm not convinced that motion is causing the cracking problem. My manifold typically cracks in the center area. I've even had it...

I bought .99 cent cup holders that hook onto your door. I drilled a hole in the back and removed the shifter cover (I have an '86 manual but auto's should be the same). I used zip ties to hold onto the metal brackets under the shifter cover and through the hole in the cup holder. Now they...
