i had a tfi go bad on me also, ran fine, would only backfire and cough if i stabbed the gas to fast, if i slowly floored it it was fine. i never thought of it being the module, so iswapped it w/ another bad one a buddy of mine had that would cause a rough idle but run good otherwise, and my caridled rough and i could stab the gas fine. those things do all kinds of weird stuff.

my mechanic says that it is definetly missing...the little rock in the motor at idel is bad enough to say its a miss and possibly a dead cylinder. i didnt think it was that bad when i bought..didnt realize that would be a miss since on my old dsm when it would miss u knew it. just keeping everyone posted he will be finishing up with it today hopefully tomorow. possibly new motor but we will see.

My car has never done that....LCBlackDeps did and it turned out to be his pickup coil in the distributor.

well spoke to previous owner...told me their mechanic said there was oil in the intake mani and tb but said they didnt know where it was coming from and gave the car back to her...yet to do a tune up today but comp test tomorow...along with starting the tune up...guess the oil in the intake would be my valve seals...

preciousroy

oil in the intake would not be your valve seals. a little bit of oily stuff is normal, alot means the pcv is sucking up too much for some reason. either you have so much piston ring blow by that oil is being forced through the pcv, you have different valve covers or the baffles are cut out and oil is being sucked through that tube that goes to the tbody, or you just need one of those pcv oil seperator things.but i still dont really see this being your low on pwr problem unless it is actually bad blow by but you would have blue smoke from your tailpipes from burning oil

i do have a little smoke when its cold or if its been sitting for a bit but thats it...girl told me pcv valve was replaced to but she didnt say how long ago that was...the mechanic couldnt have been that good if they gave her the car back bc they didnt know where it was coming from...mind you girl is a friend so she wouldnt say something about the car that wasnt tru...i dont know where to start bc the car isnt burning really any oil except for what i said before...

preciousroy

if you haveBLUEISH smoke on startup then thats a sure sign of valve seals, but dont confuse that smoke w/ normal whitish smoke from condensation on first startup. but still, valve seals will not put oil in your intake, maybe a little bit right were the valves are in the head but thats it.

ant0045

no its definetly bluish but the funny thing is it doesnt really smell like burning oil ive smelt before...

idk maybe it has to do with what in the module goes bad or something cuz it would start then when i started driving down the road it would start to bog down on me and then just shut off and i couldnt figure out why.. i replaced the blaster coil thinking it was that cuz i wasnt getting spark.. but then it turned out to be the TFI module.. and she ran fine after that

ant0045

not that bc its not shuting off...it will throw a random CEL than the CEWL will go on wont stay on for mor than 20sec max
