2001 escape 3.0 engine is giving me a headache . It starts and will ideal no problem but as soon as I step on the gas the engine sputters and coughs but it does race up . I put in new intake seals , new sparks plugs , and a tps and cleaned the maf sensor . it shows no codes so what am I missing ? can it be a fuel system problem ?? what should I be looking for ?? p.s. I don't have the money to put it in a shop so any ideas would be a big help . Thanks

 

Unplug the MAF and see what it does .

 

It sounds as if it could be plugged cats. Search Youtube for diagnosing clogged catalytic converter.
