'02 GT Intermittent problem (Reward for help)

[stangsdado]

As I stated earlier I had the same problem with my 02 GT. I installed a set weapon X COP's and problem solved. How many miles are on it? Have you washed the engine recently? My car didn't throw any codes at all. I also pulled each connection to all 8 coils and each one made the engine stumble. Sounds like a weak Coil.

I think you're right. However, now that they've been cleaned and dried, the car's not doing the vibration anymore. New spark plugs may have been unnecessary but the car's going to a good friend of mine so I'm not bitter.

Working on the ABS problem now but I have no idea where the sensors are. I've done all the breaks on this car so I'm familiar with it. I've even done one caliper when it started leaking brake fluid but I've never paid attention to any sensors...

Check the sensor connections and clean them. Chances are its probably the ABS module.

Damn. That sounds expensive.

OK. So I took out every single wheel sensor, cleaned them, tested resistance to 50 ohms as specified, put it all back together and the ABS light is still lit. Can I reset this somehow? Any way to get codes other than going to the dealer? Can anyone understand this page?

there is a test plug on the bottom of the abs module, make sure its seated well. Also, Check brake fluid level

So I called up my long time mechanic (owner) and he said he'd scan for me for $35. As I was pulling in, I see him leaving so I knew I'd have to deal with someone else. So I walk in, and his son takes the car. He comes back and tells me the ABS Control Module is most likely fried cause there is no communication. Just as I was about to call it quits, Frank (my mechanic) walks in and tells his son to take a deeper look. So his son breaks out the wiring diagrams and checklists and such and finally finds out that there is no power to the module upon ignition. He checked the ground and the fuse and those are good. Frank tells me it'll be $75 per hour until he finds out where the problem is.

I took the car back thinking I'll look at it but I think I'm going to just take it back to him and hope it's a 1-2 hour job.

Any opinions?

First, remove that 255 pump. There is no reason to have it and it probably is hurting your car. Second, clean your IAC and replace your TPS. Also, replace your fuel filter.

With the leaky coolant, sounds like you have a cracked intake. Get some starting fluid, spray it around your intake. If you car rev's, you either have a vacuume leak(cracked vacuum line) or you have a cracked intake. Its hard to determine the issue when you have that 255 pump though.

To test the ABS, go out on a empty street and slam the brakes on. If it locks up, its ABS, if it doesnt, your ABS is fine.
