does the engine light stay on?if so,can you give me the computer codes?
the engine light comes on for a while (stays on about 15 min. & goes off it will come back on again after about 15 to 20 min. and stay for a while) The shop here said that they can't pull a code on it. I put a new throttle position sensor on it, but may have messed it up I did'nt take the battery cables off, should I try another TPS?
no..i dont think its the tps...first..remove and clean the egr valve with carb cleaner..it may be sticking open a little causing a vacuum leak from the exhaust...also,remove the iac[idle air control]valve and clean it also,these will get black soot and carbon on them and not work right sometimes...but..the problem may be the egr solenoid,,[this is what the vacuum line from the egr valve connects to]it may be opening the egr valve when you first start the engine..i will give you a way to get the codes without a scanner,,please print

Stored trouble codes in the ECM memory can be cleared by removing battery voltage from the ECM. To do this on S/T 10-15 models, turn ignition "Off," then remove battery positive cable or remove ECM fuse for ten seconds. On all other models, turn ignition "Off," then disconnect ECM harness from positive battery pigtail for 30 seconds. Trouble codes should be cleared after any repairs have been made performed. To prevent damaging the ECM, the ignition switch must be in the "Off" position when disconnecting or reconnecting power to the ECM.After the ECM memory has been cleared, a change may be noted in vehicle performance. To restore normal vehicle performance, drive with engine at normal operating temperature at part throttle, moderate acceleration and idle conditions until normal performance is restored.
