Ok well my car for the longest time has studdered going up hills and randomly dying with a stumble...trouble starting and would miss going around corners.

Started out......sitting at ivy tech....would only turn over every 3rd or 4th time and had to give it some gas usually with a backfire out of the tbi and it would just die. This was while parking on an incline.

I had noticed driving and turning around corners it would miss and sometimes die. The problem just got worse with each tank of gas.

I immediatly replaced the fuel filter...it was clogged and some rust came out when i blew into it. The problem still didnt go away. I changed the wires with 8.5 MSD superconductors and ac delco plugs. I had also replaced the distributer cap with an accel high performance cap and rotor. Nothing changed. I had called a mechanic that is a family friend and he said try to drive it once with the air filter off because he thought it might be rubbing the coil wires but that was a bad idea...car backfried and flames shot up and came out the cowl towards the windshield..quickly gave it some gas and it sucked the flame back in. I had a mechanic look at my car and he saw that whenever the car fell on its face and backfired it was shooting fire out of the tbi telling him that the car was lacking fuel. Went to replacing the pump and it was covered in gunk and rust and the wires had burnt up. He replaced everything the pump and the wires-ac delco gm parts. He also advanced the timing but im not sure what he advanced it to. he did not say.

I had just got the car back last night and everything went good....running 10 times better with alot more kick...well until i put my system back in the car....i noticed with it on going up hills and turning corners it now misses once again.

Could the system be drawing so much from the battery that the car misses for a second or drawing too much from the altenator? I had the battery and the alternator tested and they both tested out ok. But im not sure with my accesories on.....neons, system/so on.

I noticed that the front of my car vibrates quite a bit with the system on...could it be vibrating a ground around and not making good conection?

When i had this problem before and the starting problem i had got a code 43....Electronic Spark Control Circuit. Could this cause any of the problems that i am seeing??

Also ive heard about the fuel pump relay but im not really sure where it is located?

Went to get a car wash tonight...WIERD....As the problem states above when turning corners the car would miss.....now my subs will only bump while turning and the car wont miss!!! WTF as long as im driving a strait line my subs wont hit.....something sounds really fishy here.....im thinking one of two things...bad connection at the battery/loose ground or loose ground at the amp. The battery would make more sense seeing the car would usually miss with the system on around corners.

This is probably an off the wall question but could my car be missing by a loose ground at the amp?
