i have two problems here
1. my 98 contour 67000 miles. it ideles fine but if i am ideling and just barely touch the gas it seems like it is missing the engine starts to shake and it dont seem to be hitting on all cylinders but if i give it gas it seems fine.i recently had the vct solenoid changed and spark plugs. had fuel in the oil and had that changed also. when they tried to start my car the manifold got really really hot and they found a lady bug in the i think it is the map sensor. located on the air cleaner tube. it was up against the two wires. when i got it back i had another code p1130 which O2 sensor is this. the top one?? and could it be that it got so hot that it burned it out? i havent had the p1130 code since i had it cleared. also it seems the car heats up alot faster than it did before and gas mileage is way down.
when the car warms up to operating temp it seems to have a hesitation when pulling away from a stop.
2. when i start my car annd put it in drive with my lights on and start to take off my lights go dim for a split second than bright again. any one know what could cause these problems any help is welcome.

thanks in advance
