are you still using the AM radio that came with the car? If so, that's where the issue lies...basically, some receivers filter out interference better than others, and sometimes the parts that filter out the interference fail, and for some reason suddenly your receiver is not filtering it out. Have you changed the position or length of the antenna wire from the receiver recently? Like cut off the excess or something? If you cut off more than two or three inches of the antenna, you will have serious range or interference problems. Is it both servos glitching ? Or just one? If it's just one, try swapping them over. Is the same servo glitching ? If so, then it's the servo, if the other servo is now glitching , then again, it's the receiver. You could just change the offending servo or receiver, but the worst thing about RTRs is always the radio, receiver and servos, you should take this opportunity to buy a good radio ( I prefer nomadio or spektrum)

Tuning Engine for Power
your engine should be. You can start to adjust it for maximum performance. The first thing you should check is to make sure that when you pull full throttle the carburetor is fully opening. If you take the air filter off and pull the trigger all the way back it should be fully open. You should always keep the engine within its intended operating temperature. Going above these could and most likely will cause damage. As you lean the engine out, it will run faster and faster till you hit a point where it will overheat. When this has happened it will start to stutter, hesitate, or even stall. The engine will over heat very quickly when the mixture has been set too lean. Check the engine often when leaning it out to make sure its not overheating. When you have the mixture set correctly you will hear the engine running smoothly and have a strong-sounding high pitch when you let it wind out. Running the engine a little "rich" is always a lot better then running it to "lean".
Once again: Lean = less fuel
Rich = more fuel

Tuning the High-Speed Mixture
The high-speed mixture will affect the way engine runs at mid and high R.P.M.s. This is the main needle that you will adjust the most. Once you get you engine running good, this will be the only needle that you should have to mess with. Run the car on a smooth flat surface with enough room to let the model get up to top speed. Keep track of the speed as you slowly (1/8 of a turn at a time) lean the engine. You can lean it as long as you continue to have thick blue smoke coming out of the pipe. If the engine gets up to top speed and looses power most likely you have "leaned" it too much. You want the high-speed mixture to be lean enough to get good power and still keep the engine cool. Use a temperature gun or the "spit" test to check the temperature of your engine. Remember, you want the engine to run around 270' or spit to sit on the head for around 5-7 seconds.

Tuning the Low-Speed Mixture
The low speed mixture affects how the engine will perform at idle and low R.P.M.s. Like the high-end mixture, the "leaner" you run it the more performance you will get out of it. If it is set too "lean" it will stutter and even stall out. To properly set the low-end mixture, do the following procedures: Get the engine up to running operation temperature. Then from a complete stop pull full throttle, if the engine bogs down, you need to "lean" it out a bit. If it speeds up then bogs down, it's too "lean", "richen it up a bit. You want it to accelerate well with out stalling.

I have a Futaba 3pm FM. Both servos glitch when the igniter touches.. I am thinking receiver issue.

I only ask cause I cut it right after posting. Just a couple of hours and the sun will be up and i can try it out. ....

By the way, takenotesbch, that first quote is one of my posts! Good to see you've been taking notes.
