i just bought a 91 camaro 305/TPI and when i bought it the guy said he had recently placed new bosch spark plugs for me but said since he put them on hes had a skipping problem and to change them back to the ac delco platinum plugs...the car has 100k miles on it and is in excellent shape...is it really the plugs that could cause the car to skip or a bad injector..the skipping happens only after i drive for a few miles when it warms up and is really annoying its like the car has no acceleration especially if i lay on the pedal and get up to a high rpm its just skips and shakes..it also idles pretty rough after its warmed up...if anyone knows what the cause could be pleaes let me know thanks...

 

If the problem started after replacing the plugs, the first thing I would do is make sure all of the plug wires are snapped all the way onto each plug, and check that each wire is hooked up to the correct plug. If you think the injectors are to blame, check that they read about 16 or 17 ohms.

 

thanks for the help i appreciate it...ill post back to let ya know if its the plugs

 

well i finally got back to workin on the car and found that the previous owner when he installed new plugs and plug wires the wires were touching the manifold and burnt through the majority of the wire...none the less he also only had the plugs finger tight and gapped incorrectly...thanks for the hlep i prolly wouldnt have thought to check the wires first...
