1996 4Runner Misfire, or Something Else?
Asked by ThatBlackCloud Feb 26, 2017 at 05:56 PM about the 1996 Toyota 4Runner 4 Dr SR5 4WD SUV
Question type: Maintenance & Repair
1996 Toyota 4Runner, 3.4
The truck hesitates very badly when getting into the gas pedal, such as
starting off or going uphill. This has been going on for a little over a year.
I have replaced the following:
- all 3 coils
- all spark plug wires
- all spark plugs (double electrode)
- all 6 fuel injectors
- both O2 sensors
- fuel filter
- crankshaft position sensor
- ran 2 bottles of 44K
None of this has made a difference. In fact the problem seems to be getting
worse.
Any suggestions?

I hate to say but the engine compression needs to be checked. When you can't get rid of a miss, then more than likely it is low cylinder compression.

Thanks for the reply. What would be the next step? Is there any way that I can test the cylinder compression?
That is what I said to check the engine cylinder compression. You can rent a compression gauge from an auto parts store.

Thanks for your reply. I did not replace the air filter. It appears to be very clean, as well as the MAF.

Do not know if your vehicle has this fuse or not but check to see if it has a ( ETCS ) Electronic Throttle Control System fuse.

No ETCS fuse, but now I'm wondering if the Throttle Position Sensor may have something to do with it...?
