my car has been running like crap!
at like 5k rpm or more it like hesitates and it like backfires or somthing is very odd also when i start i need a lot of gas to make it go and it hesitates A little.
thanks

is it hard to change opti?

 

It could be lots of things. Have you had it scanned for codes?

 

no, but it has 51k miles an it has never had a tune up (plugs and wires)
so i guess ill do that my dad works with splitfire so ill get wires and plugs
thanks what else could it be?

 

It could be Your coil, ignition module, egr, fuel, spark grounding, O2 sensors or another sensor failing. Mine did something like that and it was O2's. Heat can cause it to run like dirt. Get it scanned. that should be your first step. The PCM is designed to tell you when something isn't working right and there are many codes that don't light the SES light.51k on a 94 is preety good. Mine has 64k.

 

im real new to this can u please help me?
i need to know a place where to take it and that do codes mean
thanks

 

Call around to different shops and find the best price for a diagnostics test on your car. The Codes are identifiers for different functions that are used for diagnostics. On a 94 they are refered to as DTC codes. Diagnostic Trouble Codes. Here is a list of them. Your car OBD1. On Board Diagnostics 1.
