hi, i guess to start off i should put out that i know practically nothing about cars. so some of what im asking may be easy to answer or not, but hopefully someone can help. for the longest time now, my cougars been going extremely sluggish. just recently its been worse. if i floor it, 90% of the time, it will either take forever for the car to speed up and the rpm's creep up slowly, or when i floor it, the rpm's shoot up, but my car still barely creeps up in speed. there is a very noticeable difference from what it used to be like. im being told that the problem is the intake manifold runner controller. they are saying something about its supposed to open up at around 3000rpm but it doesnt open at all. (sorry for the confusing explanations) they are quoting me at $140 for the part. plus about another $170 for labor to put that in, and also to reprogram the pcm. my questions are, could this be the reason its acting sluggish like this? they are guaranteeing me that they are 90% sure that is it. i dont want to pay this much money just to find out it didnt do crap. also, am i getting ripped off for parts cost and labor cost? please help, im to broke to be dishing out this kinda money... especially if it isnt even the main problem. i guess i probably need to mention some stats on my car. its a 99' v6, atx. ummm... dunno what else i need. my mileage is at 66,000. my cars been acting up id guess for around 8 months, but just recently its been acting like this almost everytime i do it now. it used to just do it every now and then. thanks.
