my 03 thunderbird suddenly started to what seemed misfiring on multiple cylinders , then gets better then worse then ok and mediocre again .Engine
light appeared and disappeared a few time at full throttle but car having trouble to accelerate .I went to the smog check place when it seemed to be better for my control .I told them what happened and they checked codes although no engine lights on .The codes were P0606 P1235 and P2107
JA: Does the light stay on, or does it blink?
Customer: it blinked and didn't stay on
JA: Are you fixing your Thunderbird yourself? What have you tried so far?
Customer: Just happened a couple hours ago.I thought it was a couple cop going bad as it happened before but not sure since code seems to ppoint out to fuel pump or computer malfunction .
JA: Anything else you want the mechanic to know before I connect you?
Customer: Car had a starting problem last year .Started and then shut off .It's been fixed by replacing the reset button under the hood on the side ,Engine light stayed a little bit then disapeared .Everything was well with the car except a thermostat
housing that blew ( plastic) and put me on limp mode .That too was fixed and car was running great .I haven't put a thousand mile on the car since last year so there is few miles inbetween those events .Many months but few miles
