Guest Hitzzz Posted October 2, 2002 Share Posted October 2, 2002 I've recently been having a problem with hard starts on my 90 Reatta with 54,xxx miles... I've replaced the fuel pump relays, coil pack and fuel regulator .... when these items were once replaced it helped the hard starting for approx. 6 months then the problem returned... I want to clean the MAF sensor but I do not want to destroy it at the same time, does someone have a safe guidelines for cleaning the MAF .... type of cleaning fluid..??? should I remove the MAF for cleaning ...???? it looks like removing should be simple ...

Guest Posted October 2, 2002 Share Posted October 2, 2002 Sounds to me that you are just replacing parts without knowing why. For instance, did you measure the rail pressure before replacing the fuel pump relay and fuel related items? What's the rail pressure now with the key on and engine stopped? Do you have the hard starting problem with a cold or hot engine? What about the plugs and wires?Why do you think the MAF is to blame? If there are no diagnostics indicating an improper air flow, I would leave the MAF well enough alone.The problem you have needs to be approached <span style="font-style: italic">logically</span>, test first, then replace if the test shows replacement is neccessary. Throwing parts at a problem with no logic won't work. Link to comment Share on other sites More sharing options...
