Okay guys I will try and get to the point without details..

a few weeks ago I brought my car in for repairs I blew a water pump..they fixed it along with blowing out my opti, I argueed with them on that and got a new one, along with a tune up.

This is what was done.
Coolant temp sensor
thermostat
waterpump
flush and fill

tune up
spark plugs
wires
whole new opti put in..

now the car runs decent I can hear a little grumbling here and there like something was not right. at idle it sounds fine. but I rev it up to about 1200 RPM and its got a miss I can feel it and see it on the tach you hear the miss and the tach needle goes down..

what I would like to know is it possible to not install the optispark the right way? or you think they didnt gap a spark plug the right way? or the wire came loose..

just asking since my fiance took the car to work and Im sitting her going crazy on what to do..

also what would you say to the shop, the work is warrantied and stuff how should I say its not running right and I am pissed that I spent 1100 for a coolant problem and now I got a miss in my perfectly fine running engine before...and taking time off so that it can be fixed sucks cus I dont have the $$$ or luxury to miss a day..

 

no help??? anyone????
