So,
I had this problem a while ago, and my mechanic (HPH) said there was too much O2 coming out, so he re-sealed the intake plenum, and it was all good for about a month. Now its been getttin worse and worse as the weeks go on. So....heres what happens. Under *hard* acceleration the car begins to buck/spit/sputter at high rpm's and whenever my foot is not on the gas pedal there is backfire AKA: during shifts and under deceleration in gear. It also *someitmes* happens at a steady speed, but almost everytime under *hard* acceleration. Thanks in advance!!! -Peter It's a 1975 1.8 L Jet |
