You dont need to ground your ht lead, infact that could damage your ignition system, if in fact removing it from the plug does make it worse you then know that this cyl was firing and that ignition on this particular cyl is not your problem.

Tells me that bank (1) p0171 and bank (2) po174 are bad which bank is 1 and which bank is 2


P0171 and P0174 are lean codes. They do not mean the 02 sensors are bad. The most common cause for this especially when both banks are lean is the plenum gaskets in between the plenum and the heads. They will start to leak and cause a vacuum leak. When they leak bad enough it will flag lean codes and eventually the vehicle will start to idle rough and eventually not idle at all.

Replacing the gaskets will usually fix this problem. Sometime the intake plenum will warp and need to be replaced as well. Replacing the O2 sensors will not fix this problem.

Enginelight on, code P0171,P174


Classic! These codes typically come when the throttle body air plenum gasket cracks. The engine will usually idle rough as well. If it is idling rough, you can spray carborator cleaner around the throttle body with the engine running and you should immediately notice a difference.
The plenum gasket is about $30.00. You need to remove the fuel rails and intake manifold to replace it. Not too bad a job for a garage mechanic. Roughly 2 hours.
I let mine go for about a year before fixing it and was sorry I did after seeing how easy it was to correct. Car runs great now.
