I have a 1994 Camaro Z28. Recently it's had a few problems. I cleaned the mass air flow sensor which made it run a lot better but it still has very little high end power (high rpm). I can not figure this out. PLEASE PLEASE help if you have any ideas.

 

When is the last time you did a tune up? air filter, fuel filter, spark plugs, wires? Also, check and see if you are throwing any codes

 

Well, I have had the car for almost years now and have not done a tune up. I was considering it though. Do you know how much it would cost to have a tune up done?

 

OK, so I was driving it tonight and it sounded like it backfired and felt like it was missing and wouldn't accelerate well at all. I put some gas in it and all the sudden was running a little better but still had no power in higher rpms. I kinda got on it on the highway and got up to about 75 or 80 and the service engine soon light came on but went off in about 10 seconds after I got back down to 65 or 70. I have no idea what is causing this so if anyone has ANY ideas at all I would more than appreciate it.

 

in any case do a tune up on her, change the fuel filter. need to scann to see if u have trouble codes and let us know what they are if there are any. im thinking opti.
