bad sputtering problem
My mom has a 94 grand marquis. Ok when its cold its the worst. you have to let it warm up for ten min before you can drive it or else there is no power and sputters very bad. Even when its warm it still occurs but its drivable. The CEL used to come on and off every now and again and we could never catch it to come on when we had a scanner hooked up. We recently put a fuel filter on and now the CEL never comes on! But the problem still exist the same. Makes no sense to me. If it was the TPS wouldnt it throw a code? and also does the 94 have a plastic intake manifold and could have possible crack? Anyone come across this on a 94? Any suggestions would be helpful! Thanks ya'll

i think i just rolled out cracked intake manifold, i see the bad years are 96-01 and that problem exist more when it warms up and mines worse when its at a cold start. what could cause this without throwing any kind of code?
