it looks like a fan or a snowflake

My uncle has a 1995 Mercury Cougar xr7 with a V8 engine... recently shes been stalling out on us and refusing to start...Sometimes when we stop to turn she wont accelerate, we have hooked the car up to a computer that is supposed to diagnose the problem and it showed that it was the mass airflow sensor so we replaced it, then it showed that the EGR sensor was the problem so we replaced that but shes only gotten worse and we can't figure out what the problem is....Has anyone else suffered these problems?

oil pressure above normal. there is a leak in exhuast near the manifold on the engine. transmission is not shifting correctly but is still shifting. the engine is new.

Just got new plugs, wires, and they said fixed rubber on all vacuums? Oh and new master air sensor...

He gave it a tune up and says he fixed vacuum leakes?? Now it iduls low?? Help please

i am thinking of buying a 96 cougar that needs wiring help brake lights radio lighter trunk pop don't work i know i can fix it just want toknow ifthey are know for this problem

the bolt for the shock or strut that is on the passenger side won't come off. What do I need to do? Please HELP..... Thanks so much

have re placed the egr valve , fuel filter, mass air flow senor.it is reading codes po174 po300 po305 po306

and replaced fan, fan doesnt seen to be working but was at first

sounds like rear suspension if loose, (checked is not loose).

anyone know where the pcv valve is located on a 2001 cougar 2L engine

all the fuses,lights,relays and switch have been checked and or replaced. still does not work. but the hazards,headlights,brake lights,running lights,and backup lights work. and hazards flash in the dash but blinkers don't.

Its having trouble starting, very difficult to start. And when it does start, it has trouble staying on. It will stay on for a minute or two tops, then the egine will start sputting then die out. I already changed the fuel pump, fuel filter, spark plugs and wires, and then finally the mass airflow sensor but none of them seemed to fix the problem, what else could be the problem?

NO computer codes, shift down is ok, runs good has good power. 3.8 6

My 1999 cougar jerks and revs up and down while driving when I come to a stop it starts up slowly to get going again no smoke and doesn't shot off what could be the problem it stats doing after I've drove even just a few miles

I already checked all the fuses and the battery and alternator, everything is good. I also placed it on the computer and no codes are coming up. Anyone know what is wrong?
