Ok guys heres the deal I have a 2000 corvette, last week the check engine light came on the car started running like ****..

So i get it scanned it said bad maf sensor so we changed it still isnt fixed. changed the TPS sensor didnt help at all. I am hopeing someone here can help me..

The car idles fine and revs fine while in neutral. When you put it in gear and go to take off it bogs and almost stalls. If you have it over 3,000 rpms the car will run fine..

I dont have a clue anymore whats wrong.. any ideas?? thanks Louie

 

The scan didn't say, "bad maf sensor" it had to say something else...check engine lights don't tell you what component to replace, they tell you which system to trouble shoot. Tell us exactly what the codes were.

 

werd...whats the codes?

 

Well The shop i live by put the scanner on it and thats what the code was, and not there isnt any codes and the computer is clear thats why i dont understand whats going on with it..

 

Check all the connections on the air path from the filter to the front opening of the intake manifold. An air leak can give those symptoms.

Yep, I had the same problem with my 'zip tie mod' coming loose where the funky rubber tubing mates the filter housing.

Also as already mentioned check the codes: Hold 'Options' & hit 'Fuel' button 4 times fast to access and write-down codes if any.

 

ok guys here the codes

P 1516 IMRC Imput error bank 1

P 1220 Series Throttle Control System Malfunction

P 1120 Throttle Position Sensor out of range

P 0101 MAF range/ performance

What do you guys this i put a new maf sensor in and a TPS sensor

 

Not an air leak. I've not seen those codes on my 01 or 02 Z.

Before starting to change parts, I'd suggest reviewing the Service Manual refs for those codes.

I already changed those parts, it didnt help at all

 

What parts are you referring to?

Ranger

 

Hmmm not sure about those.
Have you taken apart the intake assembly and checked all the connections and the throttle body?

 

ok I know it's an old thread, but now I'm getting the po1120 [tps out of range].I changed the tps over a year ago & the car ran fine.now it just goes into limp mode & won't even let me clear the code.I disconnected the battery& reset it, but the 1120 code came back...anybody??

 

A wild guess would be bad injector/injectors...............smells real similar to what I had on an 89' years ago.

 

Man...I hope not! thanks!
