I had a guy come over and install a new radiator cuz i had a radiator leak.
On a 1996 chevy lumina there are engine brackets that hold the engine to the car basically. when u unbolt those brackets the engine shoots back. so while trying to pull the engine back after fixing the radiator the guy broke one of the fuel injectors and had to replace it. im not really sure if he put it back in right because ever since that has happened the car hasnt been running right. It drives really sluggish and now the check engine light is on and i smell gas a little when i cut the car on. i have no idea whats wrong with it and i would really appreciate it if someone could help me.

Re: check engine light stays on
You might check the injector that replace check for leakage make sure that you put the o ring cause if not it make a leak that causing your complain or look for a leak in the fuel lines maybe you hit something and it could leak in the engine bay and burn that is why it smell like gas always double check your work to make sure that you eliminate the complain..
Take it to a parts store like Autozone or Advance. Also any maintenance shop. They can run a check on the engine light to get a code. The code will tell you what the computer thinks is the problem. My Toyota, it was the oxygen sensor, which looks like a spark plug and is attached to the exhaust system. I would also just look around and see if there is something else that is not connected. Could be a wire connection or a hose, a loose vacuum hose can make a big difference in the performance.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Possible that the radiator is dirty and needs to be flushed out and refilled with new anti rust/coolant. Also check for low level of water after a day and if so there is leak in the system which must be sealed. Also the radiator cap could be damaged. finally make sure that the timing and tuning of the engine is in order.
When draining the coolant, keep in mind that cats and dogs are
attracted by ethylene glycol antifreeze, and are quite likely to drink
any that is left in an uncovered container or inPuddles on the ground.
This will prove fatal in sufficient quantity. Always drain the coolant
into a sealable container. Coolant should be reused unless it is
contaminated or several years old. To avoid being burned, do NOT remove
the thermostat housing cap while the engine is at normal operating
temperature. The cooling system will release scalding fluid and steam
under pressure if the cap is removed while the engine is still hot.

Hello, there is a chance that you will not be able to pull codes out of your lumina the way you are trying to. There is a model changeover that GM had started implementing On Board Diagnostics2 in 95, that you must start pulling codes out like the 1996 but use the old style connector. I have had the same problem with a 1995 Monte Carlo I had. You may want to clean the throttle body and make sure you have no vaccum leaks anywhere . Just check by spraying carbuerator cleaner all over the engine, if the engine changes speed or sound it has found a leak. Thank You
A radiator cap with a bad seal will allow the coolant bottle to stay full but the rest of the coolant system to get low. Water pumps on the V6 engines will leak only when the engine is running. But you will find coolant on the right side of the car. If you do not see coolant on the ground where you park it could be the intake manifold gaskets leaking. This has been a big problem for GM, run a Google search. You can take it to a service center and they can test the system and tell you where the coolant is going.
Hi there .... the best thing to do right now is to take it somewhere like autozone and get the car scanned for codes. Once you have the codes you can post them here and we can help you with it. Without codes it is a little difficult to diagnose.
