I have a 94 gt 5.0 and when I hit the gas the car boggs or bobbles till it hits 2000 rpm then runs fine ... It is a auto and I dont know why is does this so I really need help thanks

first thing to usually do isrun a koer test and check for codes, if none exist, look for vaccum leaks if none try cleaning the maf, then if that doesn't help, has the car had a full tune up lately?? ie..cap, rotor, wires, plugs??

malo012000

I have changed the cap rotor plugs and the car does this only when warm ...I also did the code test and pulled these codes 111,118,157,158,181,189,212and327 then I cleared them and got 564and 111 then cleared them again and drove it around all week and got 111,118,181,189,212 I have changed the 02 sensors and the cts with no change help me please

mjr46

I have the discription of them but dont know how to fix them

mjr46

so list a brief description of codes

111 system pass
118 - ECT Sensor Circuit Above Maximum Voltage of 4.6 volts (O), ECT sensor circuit has intermittently failed above the maximum of 4.6 volts (M)
157 - MAF sensor went below 0.4 volts during the last 80 warm-up cycles
158 - MAF sensor went above 4.5 volts during the last 80 warm-up cycles
181 - Right side still lean, at richest adaptive limit, during part throttle
189 - Left side still lean, at richest adaptive limit, during part throttle

have you tried cleaning the maf sensor?? also for the ect code, you did warm the vehicle up before doing the koer test right??

malo012000

Yes the car was warm and tell me something good to use to clean the maf
also thanks for responding to me

agreed.. Clean the MAF.. You can buy MAF cleaner that is safe at any autoparts store.. Ive heard ppl use brake cleaner too..
