ok here it goes
this is what i know so far
1 spark plugs all have a nice brown color (iridium plugs with about 5000 miles)
2 no vacuum leaks or at least i can't find one
3 have not checked injectors i will when i bring my noid light home
4 IAC has been changed 2 years ago and i just cleaned it
5 O2 sensors are original as far as i know both are a little corroded so I am planning on replacing them
6 did not check coil as it too was replaced about 2 years ago and plugs look good
7 fuel pressure will be checked when i bring my fuel pressure tester home
8 CEL is off and there are no codes
9 Catalytic Converter was hollowed out due to it starting to come apart and no money at the time to replace it (i will replace it with O2 sensors)
10 MAP sensor was cleaned also (air filter is also clean)
misses at idle and seems to have trouble warm or cold and is a little sluggish in 4th at 35 to 40 mph. accelerates fine and Gas mileage seems fine. so is there anything that i missed or can be suggested.
one other Question can 3.0l fuel injectors be used on a 4.0l?
