With no consistency my 2.0 fi car will sputter and shutter. Its hard to tell weather its a lack of fuel or a lack of spark. Its fairly speratic but constant once the car is warm. What I usually have to do is stomp it or feather it past 4k rpm and it runs fine above 4k.
Things ive fixed/replaced New oil and filter new fuel filter Checked/replaced any bad vacuume hoses replaced and calibrated the tps checked mps checked aar. Stays closed 24/7 which is better than open randomly new cap new rotor Adjusted timing to the best of my ability (IMG:style_emoticons/default/blink.gif) I've owned this car for over a month now and it has never run properly due to this problem. Today im going to check the injector points and do a valve adjustment. I can hear the injectors firing with the key in the on position but they could still have issues I suppose. Help me... carbs are calling my name. (IMG:style_emoticons/default/bs.gif) (IMG:style_emoticons/default/WTF.gif) |

QUOTE(JtoTheBeezy @ Aug 14 2014, 02:20 PM)  Really? Sears sells both timing lights and dwell meters. You need one of each to tune up a 914. It is THE most important thing you can set and adjust on the car, maybe more important than the valve adjustment IMHO... I can burn up the motor if down by ear, it can do damage. Get some tools and welcome to the fun. |

Get some tools and welcome to the fun. I definitely have a timing light. Timing marks is what im missing. When I Time it to the mark I see it runs like crap. I had it at 3500rpm when I did it. Advanced it a little bit more than the mark. Ive also realized that it is for sure backfiring so for some reason my car is refusing to burn the fuel. How do I check a cht? |
