Question about 1986 Toyota Corolla 2 Door
I have a 1986 Toyota Corolla 1.6 Litre, 5 speed manual. The car is like new and runs like a top as long as I am giving it gas. The problem is this - when I take my foot off the gas (decelerate) it bucks and farts, this problem disappears if I depress the clutch or give it gas. Its driving me nuts. Any suggestions??
If I understand your concern, you have backfiring when decelerating, if yes, a possibility is that your air/fuel ratio is too lean, there is too much air and/or too little fuel. This could also be brought about by using free breathing air filter (such as K & N) instead of the original air box/filter and no re-jetting/re-calibration done. Either that or the exhaust system has been modified or replaced with free flow, headers or sport tuned. If yes, then either the carbs have not been re-jet or the injector has not been re-calibrated. It may also require re-mapping of the ECU.
Depressing the clutch when decelerating disengages the load and therefore no engine breaking is happening.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
