i need help quick
i need help quick my TA has been runnin like crap. it idles somewhat fine until i put it in reverse or drive. then it starts shaking like it wants to turn itself off but it doesnt. it sounds like a car with a huge cam. i took it to a local shop and the guy told me that 2 cylinders were misfiring.(cylinders 4 and 7) he said it could either be the coil packs, spark plugs, or the injectors. ive already changed out the coil packs for both those cylinders with brand new ones, and its still runnin like crap.the next step would be to change the spark plugs. im just wondering if the spark plugs may be the problem or will it really be the injectors? the spark plugs it has right now are the bosch platinums and i keep hearing that those plugs are no good. so im thinking it may just be the plugs. have any of you guys had this happen to you? i just want to get my car back up and running by this weekend and i need some helpful knowledge from you guys. thanx.
how long have you been running the Bosch plugs? If you've had them for awhile, and been running ok, it wouldn't be first on the list. Any odd engine noises? Find someone with a decent scan tool, swap injectors around (namely the 4 and 7 injectors) and see if the misfire follows. Try to isolate the issue before spending any $$$ on it.

I had random misfires show up, car ran like it wanted to choke itself, strong smell of fuel, and generally bogging itself down. Are those what you're seeing? If so, it could be an O2 sensor. The good news is, they're easy to replace. The bad news is, they're not terribly cheap (~$80-90 each).

Go to an O'reilly's and get some NGK tr55's, they should already be gapped. If that doesn't work then try the O2 sensors. I've been through the same stuff, its trial and error.

Oreilly's part # for the v-power TR55's is 3951 i believe. Why did you change the coils before the plugs? Plugs are way cheaper. I usually start with the cheaper stuff when i try to fix a spark issue. I would have done plugs, then wires, then coils, but that's just me.
iam having the same problem right now, itwas fine untili hit a big *** puddle of water yesterday trt helped me and ran the codes its my o2s so i would say check that if nothing else works because yours is doing exactly what mine is doing!

yea. but my friend has a code scanner and he deleted it for me. so now its not on at all. and there are times when all the gauges and the lights get dim while this stuff happens and then it just kicks back and everything will be fine for a lil bit. i just changed the plugs and that didnt solve the problem. so on to the next step.
i just checked both injector fuses and that wasnt the problem. i guess ill take your advise volcanic and try the o2's next. i have a spare set from my cats. and to everyone whos posted, i seriously appreciate it.
