Hey Paul,


There is only one radio suppression relay, which is located under the hood, usually attached to a strut tower. There is also a fuel pump relay. That is located in the fuse/relay box located in the dash behind the ashtray. When these problems present themselves intermittently (especially in damp weather), its often because of dirty ground connections under the hood. Take them off one at a time, and clean them with fine sandpaper or a wire brush. Also check out the condition of the battery cables. Make sure they are clean and tight. There are ground connections on the right fender, above the battery, and several that attach to the engine and body. You may want to clean the idle air motor if you haven't done it already. Another thing to look at is the impulse sensor located towards the rear on the bellhousing. If the insulation on the wire is broken, it should be replaced. You may want to check the adjustment of the throttle body, its switch and the throttle linkage. These can cause the problems you're experiencing. Check out the FAQ on how to set the throttle body/switch and linkage.
