coil pack trouble

[dragracin1992]

my first coil pack is bad so i got another one off ebay but the connector to plug the pack in is different. so does that mean the coil pack wont work with my car.my car is a 93 atx im not sure what kind of sho this came off of but says from an 89-94.any feedback on this will help.

 

[dragracin1992]

well i cut off the guide and plugged the coil pack in and it still has a misfire what else could it be ive already done plugs and wires.
what about the dis module what does that do. the symptons of my car are its idling rough at 500rpms
and whne in park and floored it only will go to 2500rpms and still hace a miss. when u drive it the secondaries seem to come on at 2000.so is this ignition related or what im stumped. can someone please help me. shrug

Did you check your CODES??

You guessed that the coil pack was bad and spent money for nothing. Are you seeing the CHECK ENGINE light? If not, the source of the misfire is either the plugs or the wires. What brand and type of plugs are you using? They should be the Motorcraft AGSP32PP. What wires are installed? They should be either the WRE-4081 or the WR-4033 that also fit the 3.2L and are less expensive. Is there oil in the plug wells? What is the plug gap? Did you inspect for arc strikes down the plug insulators? Many questions that we cannot answer, only ask.

An errant DIS module would provide an error code. Don't know how to check them? Follow the links at the bottom of my signature.

The ATX has a rev limiter in neutral and park to prevent the engine from spinning more than 4,000 rpm to protect the transaxle. If the secondaries are actually opening well below 3,950 rpm, then the intake runner control system is not plumbed properly with the vacuum lines or the vacuum accumulator has been damaged.

Now as far as the coil pack goes, I've had them tested and was told that I had a couple of weak coils, but there wasn't any code coming up for this. Does this still mean that a new coil pack is warranted?

 

[dragracin1992]

i did the codes like u guys said and came up with these

koeo: 172,176,181,186,189,216,332

koer: 116,332

balance test 30 and 40

if anybody can help me pinpoint the problem it would greatly be appreciated.

172 - Oxygen sensor not switching - system is or was lean - Single Right or Rear HO2S

176 - Oxygen sensor not switching - system is or was lean Left or Front HO2S

181 - Fuel system was lean at part throttle Single Right or Rear HO2S

186 - Injector pulse width longer than expected or Mass Air Flow (MAF) lower than expected

189 - Fuel system was lean at part throttle - Left or Front HO2S

216 - Primary circuit failure - ignition coil 2

332 - EGR did not open/respond during test or if memory code did not open intermittantly

 

[dragracin1992]

i know what they meant just what would they have to do with my problem.

 

[wood_e]

do you have your plug wires in the right order?

 

[dragracin1992]

yes i do have my plugs in the right order and and the correct gap.

 

[dragracin1992]

can anybody help me pinpoint what my problem could be

Coil pack, DIS module, or interconnecting harness.

I would say the DIS module. I worked on a friends SHO. He had coil circuit number 3 bad i believe. We swapped out coil packs and it still did it so we swapped out the DIS module and that was the problem.

Hello, i have a 91 mtx sho it had what sounds like the same prob no check engine light and missing badly first did 60k was due badly 2nd found firing order wrong and code said problem with coil 2 and kicked myself after replacing it still no luck then the great guys at this forum told me how to do a dis pulse check there it was all fixed hope this helps.. autozone has a good price on the dis module under $100....
