Default Help please !!! Reduce engine

Hello everyone,

I have a 98 c5 for about five years now and I really love her but man she has been nothing but problems for me. When I purchased her she would throw a p-1125 , p-1276 code . I had the app sensor replaced and she worked fine for four months. Shortly after that it began throwing the same codes every few months, so I replaced the tac module and everything worked fine for about a year almost two and now it's throwing the following codes p-1125,p-2527,p-1276,p-1281,p-1286. I just don't know what to do anymore.... Now I can only get a few miles before It throws all of the listed code and the engine goes in reduce engine speed " service traction" and I can't drive over 30 mph . If I turn the car off for a minute and and turn the car back on everything is fine for a few miles...... Someone please help

Do you know how to clear your codes? That will get rid of your reduced power. Did you do a search for those codes? Check grounds. Battery connections. I had similar problems. Cleaned all the grounds I could find. Installed new battery and cleaned cables. Been ok ever since. Good luck.

Thevcar hasn't been in a wreck that I know of. The car does have staggered rims and tires..... 18s in rear and 17s up front and the car has also been displaying low tire pressure... Do you guys think this is the issue?

17 front and 18 rear are stock rim sizes....what tires you have on there.....could be in question....but it's not going to cause a P1125 code. By the way, there is no such code as a P2527....I take it you meant "B2527".

You are correct, I meant to say b-2527. My tire size are as following, 245/45/17 and 275/40/18 and the rear tires are looking a little worn down they probably have about 35-40% life.

Can someone send me pictures of all the ground connectors I can check in order to ensure adequite connection.
