Shakes or Wobbles problem
1994 Ford Thunderbird 6 cyl Two Wheel Drive Automatic 120000 miles
----------------------------------------------------------------
99000 mile I put headgaskets on the car they leaked water. I had a lean code and a MAF code "voltage drop below .5" on the MAF sensor (of.4volt meter) eveything I checked or replaced is border line or slighly less. I have replaced several sensors and fixed two vacum leaks I tried a used ECC >> nothing seems to help the cold start issue. When you cold start the car in the morning and the idel rpms is high and then drops, I put the car in gear and back out it trys to stall or runs rough then the idel comes back up and the car seems to run fine. it doesnt seem to be all the time. Everyonce in awhile at a traffic light itll run rough in gear. tests say check darn near everything this trans ,emissions, fuel pressure 40 to 28 running... not letting the car warmup etc. could use help?

check out the air by pass valve this helps with the idle it has a diaphram that wears out
