Maybe check your spark plugs? sounds easy but if the firing order is out of order it will misfire quite bad....hope this helps!

Rough running 86 4runner after e85 put in!


very likely the fuel injectors are damaged, replace them, the fuel pressure regulator and all rubber fuel lines, also pull the gas tank and replace the short rubber hose at the electric fuel pump, I know this is expensive but even a few miles of running would have wrecked havoc on the rubber components, that rubber debris will flow through the fuel system and will plug the injector's, E85 melts it and skin for that matter.

If your car works fine when you push the gas but bogs in normal conditions it may be your timing is off.

Runs rough


How long have you had this problem? It could just be a bad tank of gas. Other things to check:
1. fuel pump and filter
Could be running on only 5 cylinders due to
2. spark plugs/wires
3. plugged fuel injector
Any problems with electrical? Like lights dimming at same time as running rough?
4. could be bad alternator putting excessive load on engine.
