Recently I had head pulled to drilled out a plug, after they put it all back in the idle was really really rough, they "fixed" it once, then twice but it still is lacking alot of the power it had before they got it.

Any ideas what they could hve screwed up? Im thinking the computer program is still off but im not sure.

Opinions?

 

so they pulled a head drilled and put a sleve in and tapped it for a new plug? id check ur ignition coil pack plug wire and spark plug. i dont see what ur computer program would be messed up. but if u want unplug the battery for about 30 min and it should reset any codes and would tell u if theres a bad program.

 

essentially yes, i was having huge power loss t 3000 rpm, it was like hitting wall and i couldnt get the needle over 3k, then they "fixed" that and now the needle can go to 4500rpm with no problem but im not going anywhere. They put all new plugs and wires in but im stumped on the power issue and think im crazy.

 

how many miles? u could have a fuel pump problem... FPU or injectors... or the contacts on ur coil packs could be worn out

 

67k miles just put injector cleaner in and the did a full fuel system treatment, and put a new fuel filter in. I just have a hard time swallowing that I had NO issue with power before they got to it and now Im screwed, they must have done something Im thinking

 

no doubt...take it to autozone and get em to check codes see if anything comes up...

 

Is the cam timing chain a tooth off?
Any CEL lamp on?
Any codes?
Intake gasket leak etc.
They have to make good on there job.
Some one has to take a look at these things because it won't fix it'self.

 

there are codes, running lean, im guessing o2 sensor, i guess i will have the cam timeing checked, im at a loss really

 

if its runnin lean check for vacume lines but sounds like ur MAF is bad or dirty
